Support concurrent refresh of refresh tokens (#39559)
This is a backport of #38382

This change adds supports for the concurrent refresh of access
tokens as described in #36872
In short it allows subsequent client requests to refresh the same token that
come within a predefined window of 60 seconds to be handled as duplicates
of the original one and thus receive the same response with the same newly
issued access token and refresh token.
In order to support that, two new fields are added in the token document. One
contains the instant (in epoqueMillis) when a given refresh token is refreshed
and one that contains a pointer to the token document that stores the new
refresh token and access token that was created by the original refresh.
A side effect of this change, that was however also a intended enhancement
for the token service, is that we needed to stop encrypting the string
representation of the UserToken while serializing. ( It was necessary as we
correctly used a new IV for every time we encrypted a token in serialization, so
subsequent serializations of the same exact UserToken would produce
different access token strings)

This change also handles the serialization/deserialization BWC logic:

- In mixed clusters we keep creating tokens in the old format and
consume only old format tokens
- In upgraded clusters, we start creating tokens in the new format but
still remain able to consume old format tokens (that could have been
created during the rolling upgrade and are still valid)

Resolves #36872

Make security tests transport agnostic (#39411)
Currently there are two security tests that specifically target the
netty security transport. This PR moves the client authentication tests
into `AbstractSimpleSecurityTransportTestCase` so that the nio transport
will also be tested.

Additionally the work to build transport configurations is moved out of
the netty transport and tested independently.

Switch internal security index to ".security-7" (#39422)
This changes the name of the internal security index to ".security-7",
but supports indices that were upgraded from earlier versions and use
the ".security-6" name.

In all cases, both ".security-6" and ".security-7" are considered to
be restricted index names regardless of which name is actually in use
on the cluster.

[BACKPORT-7.x] Fix TokenBackwardsCompatibility tests (#39294)
This change is a backport of  #39252

- Fixes TokenBackwardsCompatibilityIT: Existing tests seemed to made
  the assumption that in the oneThirdUpgraded stage the master node
  will be on the old version and in the twoThirdsUpgraded stage, the
  master node will be one of the upgraded ones. However, there is no
  guarantee that the master node in any of the states will or will
  not be one of the upgraded ones.
  This class now tests:
  - That we can generate and consume tokens before we start the
  rolling upgrade.
  - That we can consume tokens generated in the old cluster during
  all the stages of the rolling upgrade.
  - That while on a mixed cluster, when/if the master node is
  upgraded, we can generate, consume and refresh a token
  - That after the rolling upgrade, we can consume a token
  generated in an old cluster and can invalidate it so that it
  can't be used any more.
- Ensures that during the rolling upgrade, the upgraded nodes have
the same configuration as the old nodes. Specifically that the
file realm we use is explicitly named `file1`. This is needed
because while attempting to refresh a token in a mixed cluster
we might create a token hitting an old node and attempt to refresh
it hitting a new node. If the file realm name is not the same, the
refresh will be seen as being made by a "different" client, and
will, thus, fail.
- Renames the Authentication variable we check while refreshing a
token to be clientAuth in order to make the code more readable.

Some of the above were possibly causing the flakiness of #37379

Rebuild remote connections on profile changes (#39146)
Currently remote compression and ping schedule settings are dynamic.
However, we do not listen for changes. This commit adds listeners for
changes to those two settings. Additionally, when those settings change
we now close existing connections and open new ones with the settings
applied.

Fix failures in SessionFactoryLoadBalancingTests (#39154)
This change aims to fix failures in the session factory load balancing
tests that mock failure scenarios. For these tests, we randomly shut
down ldap servers and bind a client socket to the port they were
listening on. Unfortunately, we would occasionally encounter failures
in these tests where a socket was already in use and/or the port
we expected to connect to was wrong and in fact was to one of the ldap
instances that should have been shut down.

The failures are caused by the behavior of certain operating systems
when it comes to binding ports and wildcard addresses. It is possible
for a separate application to be bound to a wildcard address and still
allow our code to bind to that port on a specific address. So when we
close the server socket and open the client socket, we are still able
to establish a connection since the other application is already
listening on that port on a wildcard address. Another variant is that
the os will allow a wildcard bind of a server socket when there is
already an application listening on that port for a specific address.

In order to do our best to prevent failures in these scenarios, this
change does the following:

1. Binds a client socket to all addresses in an awaitBusy
2. Adds assumption that we could bind all valid addresses
3. In the case that we still establish a connection to an address that
   we should not be able to, try to bind and expect a failure of not
   being connected

for read/search operations. This is more of a nit for the case of the getRole call,
that fixes a possible mapping update during a get role, and removes a dead if branch

Ioannis Kakavas 59e9a0f4f4 Disable specific locales for tests in fips mode (#38938)
* Disable specific locales for tests in fips mode

The Bouncy Castle FIPS provider that we use for running our tests
in fips mode has an issue with locale sensitive handling of Dates as
described in https://github.com/bcgit/bc-java/issues/405

This causes certificate validation to fail if any given test that
includes some form of certificate validation happens to run in one
of the locales. This manifested earlier in #33081 which was
handled insufficiently in #33299

This change ensures that the problematic 3 locales

* th-TH
* ja-JP-u-ca-japanese-x-lvariant-JP
* th-TH-u-nu-thai-x-lvariant-TH

will not be used when running our tests in a FIPS 140 JVM. It also

Integrate retention leases to recovery from remote (#38829)
This commit is the first step in integrating shard history retention
leases with CCR. In this commit we integrate shard history retention
leases with recovery from remote. Before we start transferring files, we
take out a retention lease on the primary. Then during the file copy
phase, we repeatedly renew the retention lease. Finally, when recovery
from remote is complete, we disable the background renewing of the
retention lease.

Fix intermittent failure in ApiKeyIntegTests (#38627) (#38935)
Few tests failed intermittently and most of the
times due to invalidated or expired keys that were
deleted were still reported in search results.
This commit removes the test and adds enhancements
to other tests testing different scenario's.

When ExpiredApiKeysRemover is triggered, the tests
did not await its termination thereby sometimes
the results would be wrong for a search operation.

DELETE_INTERVAL setting has been further reduced to
100ms so we can trigger ExpiredApiKeysRemover faster.

Use consistent view of realms for authentication (#38815)
This change updates the authentication service to use a consistent view
of the realms based on the license state at the start of
authentication. Without this, the license can change during
authentication of a request and it will result in a failure if the
realm that extracted the token is no longer in the realm list. This
manifests in some tests as an authentication failure that should never
really happen; one example would be the test framework's transport
client user should always have a succesful authentication but in the
LicensingTests this can fail and will show up as a
NoNodeAvailableException.

Additionally, the licensing tests have been updated to ensure that
there is consistency when changing the license. The license is changed
by modifying the internal xpack license state on each node, which has
no protection against be changed by some pending cluster action. The
methods to disable and enable now ensure we have a green cluster and
that the cluster is consistent before returning.

Ioannis Kakavas 8c624e5a20 Enhance parsing of StatusCode in SAML Responses (#38628)
* Enhance parsing of StatusCode in SAML Responses

<Status> elements in a failed response might contain two nested
<StatusCode> elements. We currently only parse the first one in
order to create a message that we attach to the Exception we return
and log. However this is generic and only gives out informarion
about whether the SAML IDP believes it's an error with the
request or if it couldn't handle the request for other reasons. The
encapsulated StatusCode has a more interesting error message that
potentially gives out the actual error as in Invalid nameid policy,
authentication failure etc.

This change ensures that we print that information also, and removes
Message and Details fields from the message when these are not
part of the Status element (which quite often is the case)

Allow custom authorization with an authorization engine (#38358)
For some users, the built in authorization mechanism does not fit their
needs and no feature that we offer would allow them to control the
authorization process to meet their needs. In order to support this,
a concept of an AuthorizationEngine is being introduced, which can be
provided using the security extension mechanism.

An AuthorizationEngine is responsible for making the authorization
decisions about a request. The engine is responsible for knowing how to
authorize and can be backed by whatever mechanism a user wants. The
default mechanism is one backed by roles to provide the authorization
decisions. The AuthorizationEngine will be called by the
AuthorizationService, which handles more of the internal workings that
apply in general to authorization within Elasticsearch.

In order to support external authorization services that would back an
authorization engine, the entire authorization process has become
asynchronous, which also includes all calls to the AuthorizationEngine.

The use of roles also leaked out of the AuthorizationService in our
existing code that is not specifically related to roles so this also
needed to be addressed. RequestInterceptor instances sometimes used a
role to ensure a user was not attempting to escalate their privileges.
Addressing this leakage of roles meant that the RequestInterceptor
execution needed to move within the AuthorizationService and that
AuthorizationEngines needed to support detection of whether a user has
more privileges on a name than another. The second area where roles
leaked to the user is in the handling of a few privilege APIs that
could be used to retrieve the user's privileges or ask if a user has
privileges to perform an action. To remove the leakage of roles from
these actions, the AuthorizationService and AuthorizationEngine gained
methods that enabled an AuthorizationEngine to return the response for
these APIs.

Ultimately this feature is the work included in:

Remove support for internal versioning for concurrency control (#38254)
Elasticsearch has long [supported](https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-index_.html#index-versioning) compare and set (a.k.a optimistic concurrency control) operations using internal document versioning. Sadly that approach is flawed and can sometime do the wrong thing. Here's the relevant excerpt from the resiliency status page:

> When a primary has been partitioned away from the cluster there is a short period of time until it detects this. During that time it will continue indexing writes locally, thereby updating document versions. When it tries to replicate the operation, however, it will discover that it is partitioned away. It won’t acknowledge the write and will wait until the partition is resolved to negotiate with the master on how to proceed. The master will decide to either fail any replicas which failed to index the operations on the primary or tell the primary that it has to step down because a new primary has been chosen in the meantime. Since the old primary has already written documents, clients may already have read from the old primary before it shuts itself down. The version numbers of these reads may not be unique if the new primary has already accepted writes for the same document 

We recently [introduced](https://www.elastic.co/guide/en/elasticsearch/reference/6.x/optimistic-concurrency-control.html) a new sequence number based approach that doesn't suffer from this dirty reads problem. 

This commit removes support for internal versioning as a concurrency control mechanism in favor of the sequence number approach.

customise its behaviour.

SecuritySettingsSource license.self_generated: trial (#38233)
Authn is enabled only if `license_type` is non `basic`, but `basic` is
what the `LicenseService` generates implicitly. This commit explicitly sets
license type to `trial`, which allows for authn, in the `SecuritySettingsSource`
which is the settings configuration parameter for `InternalTestCluster`s.

The real problem, that had created tests failures like #31028 and #32685, is
that the check `licenseState.isAuthAllowed()` can change sporadically. If it were
to return `true` or `false` during the whole test there would be no problem.
The problem manifests when it turns from `true` to `false` right before `Realms.asList()`.
There are other license checks before this one (request filter, token service, etc)
that would not cause a problem if they would suddenly see the check as `false`.
But switching to `false` before `Realms.asList()` makes it appear that no installed
realms could have handled the authn token which is an authentication error, as can
be seen in the failing tests.

Add support for API keys to access Elasticsearch (#38291)
X-Pack security supports built-in authentication service
`token-service` that allows access tokens to be used to 
access Elasticsearch without using Basic authentication.
The tokens are generated by `token-service` based on
OAuth2 spec. The access token is a short-lived token
(defaults to 20m) and refresh token with a lifetime of 24 hours,
making them unsuitable for long-lived or recurring tasks where
the system might go offline thereby failing refresh of tokens.

This commit introduces a built-in authentication service
`api-key-service` that adds support for long-lived tokens aka API
keys to access Elasticsearch. The `api-key-service` is consulted
after `token-service` in the authentication chain. By default,
if TLS is enabled then `api-key-service` is also enabled.
The service can be disabled using the configuration setting.

The API keys:-
- by default do not have an expiration but expiration can be
  configured where the API keys need to be expired after a
  certain amount of time.
- when generated will keep authentication information of the user that
   generated them.
- can be defined with a role describing the privileges for accessing
   Elasticsearch and will be limited by the role of the user that
   generated them
- can be invalidated via invalidation API
- information can be retrieved via a get API
- that have been expired or invalidated will be retained for 1 week
  before being deleted. The expired API keys remover task handles this.

Following are the API key management APIs:-
1. Create API Key - `PUT/POST /_security/api_key`
2. Get API key(s) - `GET /_security/api_key`
3. Invalidate API Key(s) `DELETE /_security/api_key`

The API keys can be used to access Elasticsearch using `Authorization`
header, where the auth scheme is `ApiKey` and the credentials, is the 
base64 encoding of API key Id and API key separated by a colon.
Example:-
```
curl -H "Authorization: ApiKey YXBpLWtleS1pZDphcGkta2V5" http://localhost:9200/_cluster/health
```

Introduce retention lease background sync (#38262)
This commit introduces a background sync for retention leases. The idea
here is that we do a heavyweight sync when adding a new retention lease,
and then periodically we want to background sync any retention lease
renewals to the replicas. As long as the background sync interval is
significantly lower than the extended lifetime of a retention lease, it
is okay if from time to time a replica misses a sync (it will still have
an older version of the lease that is retaining more data as we assume
that renewals do not decrease the retaining sequence number). There are
two follow-ups that will come after this commit. The first is to address
the fact that we have not adapted the should periodically flush logic to
possibly flush the retention leases. We want to do something like flush
if we have not flushed in the last five minutes and there are renewed
retention leases since the last time that we flushed. An additional
follow-up will remove the syncing of retention leases when a retention
lease expires. Today this sync could be invoked in the background by a
merge operation. Rather, we will move the syncing of retention lease
expiration to be done under the background sync. The background sync
will use the heavyweight sync (write action) if a lease has expired, and
will use the lightweight background sync (replication action) otherwise.

Fix NPE in Logfile Audit Filter (#38120)
The culprit in #38097 is an `IndicesRequest` that has no indices,
but instead of `request.indices()` returning `null` or `String[0]`
it returned `String[] {null}` . This tripped the audit filter.

I have addressed this in two ways:
1. `request.indices()` returning `String[] {null}` is treated as `null`
    or `String[0]`, i.e. no indices
2. `null` values among the roles and indices lists, which are
    unexpected, will never again stumble the audit filter; `null` values
    are treated as special values that will not match any policy,
    i.e. their events will always be printed.

Remove implicit index monitor privilege (#37774)
Restricted indices (currently only .security-6 and .security) are special
internal indices that require setting the `allow_restricted_indices` flag
on every index permission that covers them. If this flag is `false`
(default) the permission will not cover these and actions against them
will not be authorized.
However, the monitoring APIs were the only exception to this rule.

This exception is herein forfeited and index monitoring privileges have to be
granted explicitly, using the `allow_restricted_indices` flag on the permission,
as is the case for any other index privilege.

Create snapshot role (#35820)
This commit introduces the `create_snapshot` cluster privilege and
the `snapshot_user` role.
This role is to be used by "cronable" tools that call the snapshot API
periodically without recurring to the `manage` cluster privilege. The
`create_snapshot` cluster privilege is much more limited compared to
the `manage` privilege.

The `snapshot_user` role grants the privileges to view the metadata of
all indices (including restricted ones, i.e. .security). It obviously grants the
create snapshot privilege but the repository has to be created using another
role. In addition, it grants the privileges to (only) GET repositories and
snapshots, but not create and delete them.

The role does not allow to create repositories. This distinction is important
because snapshotting equates to the `read` index privilege if the user has
control of the snapshot destination, but this is not the case in this instance,
because the role does not grant control over repository configuration.

Track total hits up to 10,000 by default (#37466)
This commit changes the default for the `track_total_hits` option of the search request
to `10,000`. This means that by default search requests will accurately track the total hit count
up to `10,000` documents, requests that match more than this value will set the `"total.relation"`
to `"gte"` (e.g. greater than or equals) and the `"total.value"` to `10,000` in the search response.
Scroll queries are not impacted, they will continue to count the total hits accurately.
The default is set back to `true` (accurate hit count) if `rest_total_hits_as_int` is set in the search request.
I choose `10,000` as the default because that's also the number we use to limit pagination. This means that users will be able to know how far they can jump (up to 10,000) even if the total number of hits is not accurate.

we present them with a list of attributes we did get from the SAML
response to point out that the expected one was not part of that
list. This list will never contain the NameIDs though as they are
not part of the SAMLAttribute list. So we might have a NameID but

Remove index audit output type (#37707)
This commit removes the Index Audit Output type, following its deprecation
in 6.7 by 8765a31d4e6770. It also adds the migration notice (settings notice).

In general, the problem with the index audit output is that event indexing
can be slower than the rate with which audit events are generated,
especially during the daily rollovers or the rolling cluster upgrades.
In this situation audit events will be lost which is a terrible failure situation
for an audit system.
Besides of the settings under the `xpack.security.audit.index` namespace, the
`xpack.security.audit.outputs` setting has also been deprecated and will be
removed in 7. Although explicitly configuring the logfile output does not touch
any deprecation bits, this setting is made redundant in 7 so this PR deprecates
it as well.

Share `NioGroup` between http and transport impls (#37396)
Currently we create dedicated network threads for both the http and
transport implementations. Since these these threads should never
perform blocking operations, these threads could be shared. This commit
modifies the nio-transport to have 0 http workers be default. If the
default configs are used, this will cause the http transport to be run
on the transport worker threads. The http worker setting will still exist
in case the user would like to configure dedicated workers. Additionally,
this commmit deletes dedicated acceptor threads. We have never had these
for the netty transport and they can be added back if a need is
determined in the future.

Permission for restricted indices (#37577)
This grants the capability to grant privileges over certain restricted
indices (.security and .security-6 at the moment).
It also removes the special status of the superuser role.

IndicesPermission.Group is extended by adding the `allow_restricted_indices`
boolean flag. By default the flag is false. When it is toggled, you acknowledge
that the indices under the scope of the permission group can cover the
restricted indices as well. Otherwise, by default, restricted indices are ignored
when granting privileges, thus rendering them hidden for authorization purposes.
This effectively adds a confirmation "check-box" for roles that might grant
privileges to restricted indices.

The "special status" of the superuser role has been removed and coded as
any other role:
```
new RoleDescriptor("superuser",
    new String[] { "all" },
    new RoleDescriptor.IndicesPrivileges[] {
        RoleDescriptor.IndicesPrivileges.builder()
            .indices("*")
            .privileges("all")
            .allowRestrictedIndices(true)
// this ----^
            .build() },
            new RoleDescriptor.ApplicationResourcePrivileges[] {
                RoleDescriptor.ApplicationResourcePrivileges.builder()
                    .application("*")
                    .privileges("*")
                    .resources("*")
                    .build()
            },
            null, new String[] { "*" },
    MetadataUtils.DEFAULT_RESERVED_METADATA,
    Collections.emptyMap());
```
In the context of the Backup .security work, this allows the creation of a
"curator role" that would permit listing (get settings) for all indices
(including the restricted ones). That way the curator role would be able to 
ist and snapshot all indices, but not read or restore any of them.

Consistently use loopback address for ssl profile (#37487)
This change fixes failures in the SslMultiPortTests where we attempt to
connect to a profile on a port it is listening on but the connection
fails. The failure is due to the profile being bound to multiple
addresses and randomization will pick one of these addresses to
determine the listening port. However, the address we get the port for
may not be the address we are actually connecting to. In order to
resolve this, the test now sets the bind host for profiles to the
loopback address and uses the same address for connecting.

We make sure to specify include_type_name=true during xContent parsing,

for the typeless responses is currently only covered by REST tests,
but we will be adding unit test coverage for these as we implement
each typeless API in the Java HLRC.

This commit also refactors GetMappingsResponse to follow the same appraoch
as the other mappings-related responses, where we read include_type_name
out of the xContent params, instead of creating a second toXContent method.
This gives better consistency in the response parsing code.

* Fix more REST tests.

* Improve some wording in the create index documentation.

* Add a note about types removal in the create index docs.

* Fix SmokeTestMonitoringWithSecurityIT#testHTTPExporterWithSSL.

* Make sure to mention include_type_name in the REST docs for affected APIs.

* Make sure to use 'expression == false' in FullClusterRestartIT.

* Mention include_type_name in the REST templates docs.

Test: fix race in auth result propagation test
This commit fixes a race condition in a test introduced by #36900 that
verifies concurrent authentications get a result propagated from the
first thread that attempts to authenticate. Previously, a thread may
be in a state where it had not attempted to authenticate when the first
thread that authenticates finishes the authentication, which would
cause the test to fail as there would be an additional authentication
attempt. This change adds additional latches to ensure all threads have
attempted to authenticate before a result gets returned in the
thread that is performing authentication.

Add TLS/SSL channel close timeouts (#37246)
Closing a channel using TLS/SSL requires reading and writing a
CLOSE_NOTIFY message (for pre-1.3 TLS versions). Many implementations do
not actually send the CLOSE_NOTIFY message, which means we are depending
on the TCP close from the other side to ensure channels are closed. In
case there is an issue with this, we need a timeout. This commit adds a
timeout to the channel close process for TLS secured channels.

As part of this change, we need a timer service. We could use the
generic Elasticsearch timeout threadpool. However, it would be nice to
have a local to the nio event loop timer service dedicated to network needs. In
the future this service could support read timeouts, connect timeouts,
request timeouts, etc. This commit adds a basic priority queue backed
service. Since our timeout volume (channel closes) is very low, this
should be fine. However, this can be updated to something more efficient
in the future if needed (timer wheel). Everything being local to the event loop
thread makes the logic simple as no locking or synchronization is necessary.

Security: propagate auth result to listeners (#36900)
After #30794, our caching realms limit each principal to a single auth
attempt at a time. This prevents hammering of external servers but can
cause a significant performance hit when requests need to go through a
realm that takes a long time to attempt to authenticate in order to get
to the realm that actually authenticates. In order to address this,
this change will propagate failed results to listeners if they use the
same set of credentials that the authentication attempt used. This does
prevent these stalled requests from retrying the authentication attempt
but the implementation does allow for new requests to retry the
attempt.

Improve error message for 6.x style realm settings (#36876)
Realm settings were changed in #30241 in a non-BWC way.
If you try and start a 7.x node using a 6.x config style, then the
default error messages do not adequately describe the cause of
the problem, or the solution.

This change detects the when realms are using the 6.x style and fails
with a specific error message.

This detection is a best-effort, and will detect issues when the
realms have not been modified to use the 7.x style, but may not detect
situations where the configuration was partially changed.

e.g. We can detect this:

    xpack.security.authc:
      realms.pki1.type: pki
      realms.pki1.order: 3
      realms.pki1.ssl.certificate_authorities: [ "ca.crt" ]

But this (where the "order" has been updated, but the "ssl.*" has not)
will fall back to the standard "unknown setting" check

    xpack.security.authc:
      realms.pki.pki1.order: 3
      realms.pki1.ssl.certificate_authorities: [ "ca.crt" ]

Unify transport settings naming (#36623)
This commit updates our transport settings for 7.0. It generally takes a
few approaches. First, for normal transport settings, it usestransport.
instead of transport.tcp. Second, it uses transport.tcp, http.tcp,
or network.tcp for all settings that are proxies for OS level socket
settings. Third, it marks the network.tcp.connect_timeout setting for
removal. Network service level settings are only settings that apply to
both the http and transport modules. There is no connect timeout in
http. Fourth, it moves all the transport settings to a single class
TransportSettings similar to the HttpTransportSettings class.

This commit does not actually remove any settings. It just adds the new
renamed settings and adds todos for settings that will be deprecated.

[refactor] add Environment in BootstrapContext (#36573)
There are certain BootstrapCheck checks that may need access environment-specific
values. Watcher's EncryptSensitiveDataBootstrapCheck passes in the node's environment
via a constructor to bypass the shortcoming in BootstrapContext. This commit
pulls in the node's environment into BootstrapContext.

Another case is found in #36519, where it is useful to check the state of the
data-path. Since PathUtils.get and Paths.get are forbidden APIs, we rely on
the environment to retrieve references to things like node data paths.

This means that the BootstrapContext will have the same Settings used in the
Environment, which currently differs from the Node's settings.

the circuit breaking service. The default instance of BigArrays that
is passed around everywhere always uses the request breaker. At the
network level, we want to be using the inflight request breaker. So this
change will allow that.

Additionally, as this change moves away from a single instance of
BigArrays, the class is modified to not be a Releasable anymore.
Releasing big arrays was always dispatching to the PageCacheRecycler,
so this change makes the PageCacheRecycler the class that needs to be
managed and torn-down.

Finally, this commit closes #31435 be making the serialization of
transport messages use the inflight request breaker. With this change,
we no longer push the global BigArrays instnace to the network level.

Deprecate /_xpack/security/* in favor of /_security/* (#36293)
* This commit is part of our plan to deprecate and ultimately remove the use of _xpack in the REST APIs.

- REST API docs
- HLRC docs and doc tests
- Handle REST actions with deprecation warnings
- Changed endpoints in rest-api-spec and relevant file names

Deprecate types in explain requests. (#35611)
The following updates were made:
- Add a new untyped endpoint `{index}/_explain/{id}`.
- Add deprecation warnings to Rest*Action, plus tests in Rest*ActionTests.
- For each REST yml test, make sure there is one version without types, and another legacy version that retains types (called *_with_types.yml).
- Deprecate relevant methods on the Java HLRC requests/ responses.
- Update documentation (for both the REST API and Java HLRC).

Fix origin.type for connection_* audit events (#36410)
The `origin.type` field's permitted values are now `rest` or
`transport` (as the docs declare) instead of `ip_filter`.

Add DirectByteBuffer strategy for transport-nio (#36289)
This is related to #27260. In Elasticsearch all of the messages that we
serialize to write to the network are composed of heap bytes. When you
read or write to a nio socket in java, the heap memory you passed down
must be copied to/from direct memory. The JVM internally does some
buffering of the direct memory, however it is essentially unbounded.

This commit introduces a simple mechanism of buffering and copying the
memory in transport-nio. Each network event loop is given a 64kb
DirectByteBuffer. When we go to read we use this buffer and copy the
data after the read. Additionally, when we go to write, we copy the data
to the direct memory before calling write. 64KB is chosen as this is the
default receive buffer size we use for transport-netty4
(NETTY_RECEIVE_PREDICTOR_SIZE).

Since we only have one buffer per thread, we could afford larger.
However, if we the buffer is large and not all of the data is flushed in
a write call, we will do excess copies. This is something we can
explore in the future.

Remove license state listeners on closables (#36308)
We have a few places where we register license state listeners on
transient components (i.e., resources that can be open and closed during
the lifecycle of the server). In one case (the opt-out query cache) we
were never removing the registered listener, effectively a terrible
memory leak. In another case, we were not un-registered the listener
that we registered, since we were not referencing the same instance of
Runnable. This commit does two things:
  - introduces a marker interface LicenseStateListener so that it is
    easier to identify these listeners in the codebase and avoid classes
    that need to register a license state listener from having to
    implement Runnable which carries a different semantic meaning than
    we want here
  - fixes the two places where we are currently leaking license state
    listeners

Make hits.total an object in the search response (#35849)
This commit changes the format of the `hits.total` in the search response to be an object with
a `value` and a `relation`. The `value` indicates the number of hits that match the query and the
`relation` indicates whether the number is accurate (in which case the relation is equals to `eq`)
or a lower bound of the total (in which case it is equals to `gte`).
This change also adds a parameter called `rest_total_hits_as_int` that can be used in the
search APIs to opt out from this change (retrieve the total hits as a number in the rest response).
Note that currently all search responses are accurate (`track_total_hits: true`) or they don't contain
`hits.total` (`track_total_hits: true`). We'll add a way to get a lower bound of the total hits in a
follow up (to allow numbers to be passed to `track_total_hits`).
