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:

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
```

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.

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.

Update the default for include_type_name to false. (#37285)
* Default include_type_name to false for get and put mappings.

* Default include_type_name to false for get field mappings.

* Add a constant for the default include_type_name value.

* Default include_type_name to false for get and put index templates.

* Default include_type_name to false for create index.

* Update create index calls in REST documentation to use include_type_name=true.

* Some minor clean-ups around the get index API.

* In REST tests, use include_type_name=true by default for index creation.

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

* Clarify the different IndexTemplateMetaData toXContent methods.

* Fix FullClusterRestartIT#testSnapshotRestore.

* Fix the ml_anomalies_default_mappings test.

* Fix GetFieldMappingsResponseTests and GetIndexTemplateResponseTests.

We make sure to specify include_type_name=true during xContent parsing,
so we continue to test the legacy typed responses. XContent generation
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.

Security: remove SSL settings fallback (#36846)
This commit removes the fallback for SSL settings. While this may be
seen as a non user friendly change, the intention behind this change
is to simplify the reasoning needed to understand what is actually
being used for a given SSL configuration. Each configuration now needs
to be explicitly specified as there is no global configuration or
fallback to some other configuration.

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`).

Support PKCS#11 tokens as keystores and truststores (#34063)
This enables Elasticsearch to use the JVM-wide configured
PKCS#11 token as a keystore or a truststore for its TLS configuration.
The JVM is assumed to be configured accordingly with the appropriate
Security Provider implementation that supports PKCS#11 tokens.
For the PKCS#11 token to be used as a keystore or a truststore for an
SSLConfiguration, the .keystore.type or .truststore.type must be
explicitly set to pkcs11 in the configuration.
The fact that the PKCS#11 token configuration is JVM wide implies that
there is only one available keystore and truststore that can be used by TLS
configurations in Elasticsearch.
The PIN for the PKCS#11 token can be set as a truststore parameter in
Elasticsearch or as a JVM parameter ( -Djavax.net.ssl.trustStorePassword).

The basic goal of enabling PKCS#11 token support is to allow PKCS#11-NSS in
FIPS mode to be used as a FIPS 140-2 enabled Security Provider.

role mapping for users coming from different realms.
This commit adds user metadata for kerberos_realm and
kerberos_user_principal_name.

Security: remove wrapping in put user response (#33512)
This change removes the wrapping of the created field in the put user
response. The created field was added as a top level field in #32332,
while also still being wrapped within the `user` object of the
response. Since the value is available in both formats in 6.x, we can
remove the wrapped version for 7.0.

Generalize search.remote settings to cluster.remote (#33413)
With features like CCR building on the CCS infrastructure, the settings
prefix search.remote makes less sense as the namespace for these remote
cluster settings than does a more general namespace like
cluster.remote. This commit replaces these settings with cluster.remote
with a fallback to the deprecated settings search.remote.

HLRest: add put user API (#32332)
This commit adds a security client to the high level rest client, which
includes an implementation for the put user api. As part of these
changes, a new request and response class have been added that are
specific to the high level rest client. One change here is that the response
was previously wrapped inside a user object. The plan is to remove this
wrapping and this PR adds an unwrapped response outside of the user
object so we can remove the user object later on.

See #29827

Add support for "authorization_realms" (#33262)
Authorization Realms allow an authenticating realm to delegate the task
of constructing a User object (with name, roles, etc) to one or more
other realms.

E.g. A client could authenticate using PKI, but then delegate to an LDAP
realm. The LDAP realm performs a "lookup" by principal, and then does
regular role-mapping from the discovered user.

This commit includes:
- authorization_realm support in the pki, ldap, saml & kerberos realms
- docs for authorization_realms
- checks that there are no "authorization chains"
   (whereby "realm-a" delegates to "realm-b", but "realm-b" delegates to "realm-c")

Authorization realms is a platinum feature.

[Rollup] Only allow aggregating on multiples of configured interval (#32052)
We need to limit the search request aggregations to whole multiples
of the configured interval for both histogram and date_histogram.
Otherwise, agg buckets won't overlap with the rolled up buckets
and the results will be incorrect.

For histogram, the validation is very simple: request must be >= the config,
and modulo evenly.

Dates are more tricky.
- If both request and config are fixed dates, we can convert to millis
and treat them just like the histo
- If both are calendar, we make sure the request is >= the config with
a static lookup map that ranks the calendar values relatively.  All
calendar units are "singles", so they are evenly divisible already
- We disallow any other combination (one fixed, one calendar, etc)

Token API supports the client_credentials grant (#33106)
This change adds support for the client credentials grant type to the
token api. The client credentials grant allows for a client to
authenticate with the authorization server and obtain a token to access
as itself. Per RFC 6749, a refresh token should not be included with
the access token and as such a refresh token is not issued when the
client credentials grant is used.

The addition of the client credentials grant will allow users
authenticated with mechanisms such as kerberos or PKI to obtain a token
that can be used for subsequent access.

[Rollup] Return empty response when aggs are missing (#32796)
If a search request doesn't contain aggs (or an empty agg object),
we should just retun an empty response.  This is how the normal search
API works if you specify zero hits and empty aggs.

The existing behavior throws an exception because it tries to send
an empty msearch.

Closes #32256

not up to date. Time synchronization is an important part for
Kerberos infrastructure and the time skew can cause problems.
To debug further documentation explains how to enable JAAS

[Rollup] Improve ID scheme for rollup documents (#32558)
Previously, we were using a simple CRC32 for the IDs of rollup documents.
This is a very poor choice however, since 32bit IDs leads to collisions
between documents very quickly.

This commit moves Rollups over to a 128bit ID.  The ID is a concatenation
of all the keys in the document (similar to the rolling CRC before),
hashed with 128bit Murmur3, then base64 encoded.  Finally, the job
ID and a delimiter (`$`) are prepended to the ID.

This gurantees that there are 128bits per-job.  128bits should
essentially remove all chances of collisions, and the prepended
job ID means that _if_ there is a collision, it stays "within"
the job.

BWC notes:

We can only upgrade the ID scheme after we know there has been a good
checkpoint during indexing.  We don't rely on a STARTED/STOPPED
status since we can't guarantee that resulted from a real checkpoint,
or other state.  So we only upgrade the ID after we have reached
a checkpoint state during an active index run, and only after the
checkpoint has been confirmed.

Once a job has been upgraded and checkpointed, the version increments
and the new ID is used in the future.  All new jobs use the
new ID from the start
