The ML UI now provides the ability for users to annotate
time periods with arbitrary text to add insight to what
happened.
This change makes the backend create the index for these
annotations, together with read and write aliases to
make future upgrades possible without adding complexity
to the UI.
It also adds read and write permission to the index for
all ML users (not just admins).
The spec for the index is in

This change:
- Adds functionality to invalidate all (refresh+access) tokens for all users of a realm
- Adds functionality to invalidate all (refresh+access)tokens for a user in all realms
- Adds functionality to invalidate all (refresh+access) tokens for a user in a specific realm
- Changes the response format for the invalidate token API to contain information about the
number of the invalidated tokens and possible errors that were encountered.
- Updates the API Documentation

Currently, the CcrRepositoryManger only listens for settings updates
and installs new repositories. It does not install the repositories that
are in the initial settings. This commit, modifies the manager to
install the initial repositories. Additionally, it modifies the ccr
integration test to configure the remote leader node at startup, instead
of using a settings update.

This fixes two bugs about watcher notifications:
* registering accounts that had only secure settings was not possible before;
these accounts are very much practical for Slack and PagerDuty integrations.
* removes the limitation that, for an account with both secure and cluster settings,
the admin had to first change/add the secure settings and only then add the
dependent dynamic cluster settings. The reverse order would trigger a
SettingsException for an incomplete account.
The workaround is to lazily instantiate account objects, hoping that when accounts
are instantiated all the required settings are in place. Previously, the approach
was to greedily validate all the account settings by constructing the account objects,
even if they would not ever be used by actions. This made sense in a world where
all the settings were set by a single API. But given that accounts have dependent
settings (that must be used together) that have to be changed using different APIs
(POST _nodes/reload_secure_settings and PUT _cluster/settings), the settings group
would technically be in an invalid state in between the calls.
This fix builds account objects, and validates the settings, when they are
needed by actions.
As the internals have moved to java.time, the usage of TimeZone itself

Protocol wise the two are mostly identical so consumer should not see
any difference.
Note that terminology wise, inside the docs, the public API and inside
the protocol timeZone will continue to be used as it's more widely
understood as oppose to zoneId which is an implementation detail
specific to the JVM

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.

The file structure finder has timeout functionality,
but prior to this change it would not interrupt a
single long-running Grok match attempt.
This commit hooks into the ThreadWatchdog facility
provided by the Grok library to interrupt individual
Grok matches that may be running at the time the
file structure finder timeout expires.
testFailLeaderReplicaShard periodically fails because we concurrently
index to the leader group and close one of its replicas. If a
replication request hits a closing shard, we will fail that shard;
however, failing a shard is supported by the test framework - this makes
the test fail.
Previously, Math.floorMod was used for integers and longs
which has different logic for negative numbers. Also, the
priority of data types check was wrong as if one of the args
is double the evaluation should be with doubles, then for floats,
then longs and finally integers.

This commit adds deprecation warnings when using format specifiers with

The commit changes how indices are closed in the MetaDataIndexStateService.
It now uses a 3 steps process where writes are blocked on indices to be closed,
then some verifications are done on shards using the TransportVerifyShardBeforeCloseAction
added in #36249, and finally indices states are moved to CLOSE and their routing
tables removed.
The closing process also takes care of using the pre-7.0 way to close indices if the
cluster contains mixed version of nodes and a node does not support the TransportVerifyShardBeforeCloseAction. It also closes unassigned indices.

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 error message used when attempting to delete a lifecycle policy that

Redeprecates the `/_xpack/rollup` endpoints in favor of `/_rollup`.
When we cleanup the rollup in a cluster containing 6.x nodes we need to

This commit modifies BigArrays to take a circuit breaker name and
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.
1. CCR tests work without any changes
2. `testDanglingIndices` require changes the source code (added TODO).
3. `testIndexDeletionWhenNodeRejoins` because it's using just two
nodes, adding the node to exclusions is needed on restart.
4. `testCorruptTranslogTruncationOfReplica` starts dedicated master
one, because otherwise, the cluster does not form, if nodes are stopped
and one node is started back.
5. `testResolvePath` needs TEST cluster, because all nodes are stopped
at the end of the test and it's not possible to perform checks needed
by SUITE cluster.
6. `SnapshotDisruptionIT`. Without changes, the test fails because Zen2
retries snapshot creation as soon as network partition heals. This
results into the race between creating snapshot and test cleanup logic
(deleting index). Zen1 on the
other hand, also schedules retry, but it takes some time after network
partition heals, so cleanup logic executes latter and test passes. The
check that snapshot is eventually created is added to
the end of the test.
Adds a setting that indicates that an index is done indexing, set by ILM
when the Rollover action completes. This indicates that the Rollover
action should be skipped in any future invocations, as long as the index
is no longer the write index for its alias.
This enables 1) an index with a policy that involves the Rollover action
to have the policy removed and switched to another one without use of
the move-to-step API, and 2) integrations with Beats and CCR.
* 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
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).
This commit converts the watcher execution context to use the joda
compat java time objects. It also again removes the joda methods from
the painless whitelist.
* Add non-X-Pack centric rollup endpoints
This commit adds new endpoints for rollup that do not have _xpack in
their path. The purpose for this change is to take these endpoints into
6.x as well so that they can be available in mixed cluster tests too. A
follow-up change will deprecate the use of _xpack in the rollup
endpoints. And finally, in the future, we would remove the _xpack
endpoints.
* Remove import
* Fix typo
Today the `GetDiscoveredNodesAction` waits, possibly indefinitely, to discover
enough nodes to bootstrap the cluster. However it is possible that the cluster
forms before a node has discovered the expected collection of nodes, in which
case the action will wait indefinitely despite the fact that it is no longer
required.
This commit changes the behaviour so that the action fails once a node receives
a cluster state with a nonempty configuration, indicating that the cluster has
been successfully bootstrapped and therefore the `GetDiscoveredNodesAction`
need wait no longer.

Previously, we used a CamelCase to CAMEL_CASE transformation to get the
primary name of a function from its class name which led to some issues
since there are functions that we don't want to be registered this way
(e.g.: IFNULL). To simplify the logic and avoid and "magic"
transformations in the FunctionRegistry a primary name must be provided
explicitely for each function.
The same change is applied for the function resolution (when a function
is used in an SQL statement). There is no CamelCase to CAMEL_CASE
transformation but only upper-casing is applied (fuNcTiOn -> FUNCTION).
This commit creates JodaDateFormatter to replace

that future change can be purely mechanical.
This commit gets rid of the 'NONE' and 'INFO' severity levels for
deprecation issues.
'NONE' is unused and does not make much sense as a severity level.
'INFO' can be separated into two categories: Either 1) we can
definitively tell there will be a problem with the cluster/node/index
configuration that can be resolved prior to upgrade, in which case
the issue should be a WARNING, or 2) we can't, because any issues would
be at the application level, for which the user should review the
deprecation logs and/or response headers.
This is related to #35975. It implements a basic restore functionality
for the CcrRepository. When the restore process is kicked off, it
configures the new index as expected for a follower index. This means
that the index has a different uuid, the version is not incremented, and
the Ccr metadata is installed.
When the restore shard method is called, an empty shard is initialized.
ML jobs and datafeeds wrap collections into their unmodifiable
equivalents in their constructor. However, the copying builder

question in the copying builder constructor.

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.
This commit moves back to use explicit dependsOn for test tasks on
check. Not all tasks extending RandomizedTestingTask should be run by
check directly.

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
This commit hides ClusterStates that have a STATE_NOT_RECOVERED_BLOCK from
ClusterStateAppliers. This is needed, because some appliers, such as IngestService, rely on
the fact, that cluster states with STATE_NOT_RECOVERED_BLOCK won't contain anything useful.
Once the state is recovered it's fully available for the appliers. This commit also switches many of
the remaining tests that require state persistence/recovery from Zen1 to Zen2.
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`).

This commit adds an empty CcrRepository snapshot/restore repository.
When a new cluster is registered in the remote cluster settings, a new
CcrRepository is registered for that cluster.
This is implemented using a new concept of "internal repositories".
RepositoryPlugin now allows implementations to return factories for
"internal repositories". The "internal repositories" are different from
normal repositories in that they cannot be registered through the
external repository api. Additionally, "internal repositories" are local
to a node and are not stored in the cluster state.
The repository will be unregistered if the remote cluster is removed.
This commit makes `document`, `update`, `explain`, `termvectors` and `mapping`
typeless APIs work on indices that have a type whose name is not `_doc`.
Unfortunately, this needs to be a bit of a hack since I didn't want calls with
random type names to see documents with the type name that the user had chosen
upon type creation.
The `explain` and `termvectors` do not support being called without a type for
now so the test is just using `_doc` as a type for now, we will need to fix
tests later but this shouldn't require further changes server-side since passing
`_doc` as a type name is what typeless APIs do internally anyway.

It is important that all shards of a given index have the same

When building a query Lucene distinguishes two cases, queries that require to produce a score and queries that only need to match. We cloned this mechanism in the QueryBuilders in order to be able to produce different queries based on whether they need to produce a score or not. However the only case in es that require this distinction is the BoolQueryBuilder that sets a different minimum_should_match when a `bool` query is built in a filter context..
This behavior doesn't seem right because it makes the matching of `should` clauses different when the score is not required.

Introduces a debug log message when a bind fails and a trace message

This is a follow-up to #35144. That commit made the underlying

This change adds the support for rest_total_hits_as_int

The NotificationService (base class for SlackService, HipchatService ...) has both dynamic
cluster settings and SecureSettings and builds the clients (Account) that are used to comm
with external services. This commit fixes an important bug about updating/reloading any
of these settings (both Secure and dynamic cluster). Briefly the bug is due to the fact that
both the secure settings as well as the dynamic node scoped ones can be updated
independently, but when constructing the clients some of the settings might not be visible.
In the current implementation, there is a time between the
ShrinkStep and the ShrinkSetAliasStep that both the source and

that queries to during this time will query both and return
duplicates. This fixes that scenario by moving the alias inheritance
to the same aliases update request as is done in ShrinkSetAliasStep
This commit improves the efficiency of exact index name matching by
separating exact matches from those that include wildcards or regular
expressions. Internally, exact matching is done using a HashSet instead
of adding the exact matches to the automata. For the wildcard and
regular expression matches, the underlying implementation has not
changed.
The support for rest_total_hits_as_int has already been merged to 6x
in #35848 so this change adds this new option to master. The plan was
to add this new option as part of #35848 but we've decided to wait a few
days before merging this breaking change so this commit just handles
the new option as a noop exactly like 6x for now. This will allow
users to migrate to this parameter before #35848 is merged.

This is related to #34405 and a follow-up to #34753. It makes a number
of changes to our current keepalive pings.
The ping interval configuration is moved to the ConnectionProfile.
The server channel now responds to pings. This makes the keepalive
pings bidirectional.
On the client-side, the pings can now be optimized away. What this
means is that if the channel has received a message or sent a message
since the last pinging round, the ping is not sent for this round.
Today the default for USE_ZEN2 is false and it is overridden in many places. By
defaulting it to true we can be sure that the only places in which Zen2 does
not work are those in which it is explicitly set to false.
This commits changes the serialization version from V_7_0_0 to
v_6_6_0 for the authenticate API response now that the work to add

If not all primary shards have been started for an index
then the next auto follow run will try to follow to auto follow
this index again.

In #30241 Realm settings were changed, but the Kerberos realm settings
were not registered correctly. This change fixes the registration of
those Kerberos settings.
Also adds a new integration test that ensures every internal realm can
be configured in a test cluster.
Also fixes the QA test for kerberos.
Resolves: #35942
Right now using the `GET /_tasks/<taskid>` API and causing a task to opt
in to saving its result after being completed requires permissions on
the `.tasks` index. When we built this we thought that that was fine,
but we've since moved towards not leaking details like "persisting task
results after the task is completed is done by saving them into an index
named `.tasks`." A more modern way of doing this would be to save the
tasks into the index "under the hood" and to have APIs to manage the
saved tasks. This is the first step down that road: it drops the
requirement to have permissions to interact with the `.tasks` index when
fetching task statuses and when persisting statuses beyond the lifetime
of the task.
In particular, this moves the concept of the "origin" of an action into
a more prominent place in the Elasticsearch server. The origin of an
action is ignored by the server, but the security plugin uses the origin
to make requests on behalf of a user in such a way that the user need
not have permissions to perform these actions. It *can* be made to be
fairly precise. More specifically, we can create an internal user just
for the tasks API that just has permission to interact with the `.tasks`
index. This change doesn't do that, instead, it uses the ubiquitus
"xpack" user which has most permissions because it is simpler. Adding
the tasks user is something I'd like to get to in a follow up change.
Instead, the majority of this change is about moving the "origin"
concept from the security portion of x-pack into the server. This should
allow any code to use the origin. To keep the change managable I've also
opted to deprecate rather than remove the "origin" helpers in the
security code. Removing them is almost entirely mechanical and I'd like
to that in a follow up as well.

When the grouping key of a GROUP BY is a painless script (functions are
involved), the data type of the key was incorrect in certain cases
(Boolean, IP, Date). This resulted in returning wrong data type for this
columns in the query results. E.g.:
```
SELECT COUNT(*), a > 10 AS a FROM t GROUP BY a
```

Move classes under the same package to avoid internal classes being
exposed to the outside. Remove public visibility outside 3 classes:
EsDriver, EsDataSource and EsTypes.
The driver only has one package, namely org.elasticsearch.xpack.sql.jdbc

This change removes the deprecated useDisMax() and useAllFields() methods from
the QueryStringQueryBuilder and related tests. The disMax parameter has already
been a no-op since 6.0 and also the useAllFields has been deprecated since 6.0
and there is a direct replacement via defaultField.
Clients can use the Kerberos V5 security mechanism and when it

Elasticsearch server only accepted Spengo mechanism.
This commit adds support to accept Kerberos V5 credentials

- Add the authentication realm and lookup realm name and type in the response for the _authenticate API
- The authentication realm is set as the lookup realm too (instead of setting the lookup realm to null or empty ) when no lookup realm is used.
* [Rollup] Add more diagnostic stats to job
To help debug future performance issues, this adds the
min/max/avg/count/total latencies (in milliseconds) for search
and bulk phase. This latency is the total service time including
transfer between nodes, not just the `took` time.
It also adds the count of search/bulk failures encountered during
runtime. This information is also in the log, but a runtime counter
will help expose problems faster
* review cleanup
* Remove dead ParseFields
This changes the exporter code -- most notably the `http` exporter --
to use async operations throughout the resource management and bulk
initialization code (the bulk indexing of monitoring documents was
already async).
As part of this change, this does change one semi-core aspect of the
`HttpResource` class in that it will no longer block all concurrent calls
until the first call completes with
`HttpResource::checkAndPublishIfDirty`.
Now, any parallel attempts to check the resources will be skipped until
the first call completes (success or failure). While this is a technical
change, it has very little practical impact because the existing behavior
was either quick success (then every blocked request processed) or
each request timed out and failed anyway, thus being effectively
skipped (and a burden on the system).
step times were set. The assumption was that these are always set.
Tests passed, which led me to believe this was true. There is a time
when shrunk indices have their step phase/action/step details set,
but with no time information (in the CopyExecutionStateStep).
Explain API fails for these
This commit removes the use of AbstractComponent in xpack where it was
still being extended. It has been replaced with explicit logger
declarations.

This commit is related to #32517. It allows an "sni_server_name"
attribute on a DiscoveryNode to be propagated to the server using
the TLS SNI extentsion. Prior to this commit, this functionality
was only support for the netty transport. This commit adds this
functionality to the security nio transport.
added validation for complete information of step details.
also changed the rendering of explain responses so null strings are not rendered
Another thing that I changed is the format of the client-side response. I found it difficult to maintain the two subtly-different objects, so I migrated the usage of long for the fields, to Long (just as it is on the server-side).
The trigger engine did always create a new schedule data structure, when
the watcher indexing listener called an add. However the indexing
listener also called add, when the watch status was updated. This means,
that upon a watch status update the watch got retriggered, potentially
waiting a defined interval from the watch status update onwards, instead
of waiting from the last run.
This commit only updates the schedule in the trigger engine, if it
actually has changed, otherwise the existing schedule will not be
touched. This has two results
1. If a watch is updated by an execution, the existing interval will not
be touched (meaning the scheduled time will not move forward).
2. If a watch is updated by a user, but the schedule is not changed, it
will not be reset from the update (for example starting to count from 5
minutes again, if the interval was set to 5 minutes).
Furthermore some minor cleanups were applied, making variables final in
the ctor, preventing double creation of variables.
`SIGN` and `RADIANS` where wrongly overriding `mathFunction()`.
Converted `mathFunction()` to private in `MathFunction` since it

This commit adds a test for handling correctly all they possible
`SamlPrepareAuthenticationRequest` parameter combinations that
we might get from Kibana or a custom web application talking to the
SAML APIs.
We can match the correct SAML realm based either on the realm name
or the ACS URL. If both are included in the request then both need to
match the realm configuration.
This generates a synthesized "id" for each incoming request that is
included in the audit logs (file only).
This id can be used to correlate events for the same request (e.g.
authentication success with access granted).
This request.id is specific to the audit logs and is not used for any
other purpose
The request.id is consistent across nodes if a single request requires
execution on multiple nodes (e.g. search acros multiple shards).
When assertions are enabled, a Put User action that have no effect (a
noop update) would trigger an assertion failure and shutdown the node.
This change accepts "noop" as an update result, and adds more
diagnostics to the assertion failure message.
This commit adds back bundling of all deps of the sql jdbc jar. This was
lost in a refactoring of how the shadow plugin is handled for the entire
elasticsearch project.
This removes the option to run a cluster without enforcing the
cluster-wide shard limit, making strict enforcement the default and only
behavior. The limit can still be adjusted as desired using the cluster
settings API.
Add GREATEST(expr1, expr2, ... exprN) and LEAST(expr1, expr2, exprN)

Renamed `CoalescePipe` and `CoalesceProcessor` to `ConditionalPipe` and
`ConditionalProcessor` respectively, to be able to reuse them for

time.

This operator handles nulls in different way than the normal `=`.
If one of the operants is `null` and the other not it returns `false`.
If both operants are `null` it returns `true`. Therefore in contrary to
`=`, which returns `null` if at least one of the operants is `null`, this one
never returns `null` as a result.

Code that operates on-top of the engine requires all readers returned to be
unwrapped into ElasticsearchDirectoryReader. The special reader
the FrozenEngine uses wasn't wrapped.
We didn't check that the ExplainLifecycleRequest was constructed with at least
one index before, now that we do we must also make sure the tests
mutateInstance() method used in equals/hashCode checks doesn't accidentally
create an empty index array.
Closes#35822
When there is no persistent tasks metadata we could hit a null pointer
exception when executing a follower stats request. This is because we
inspect the persistent tasks metadata. Yet, if no tasks have been
registered, this is null (as opposed to empty). We need to avoid
de-referencing the persistent tasks metadata in this case. That is what
this commit does, and we add a test for this situation.
By setting the cron to 2017, we ensure it won't trigger. This makes it
easier to test because we know the job will _only_ be in STARTED,
and we can ignore INDEXING states due to transient triggers.
Closes#35779
Today we have a way to atomically persist global MetaData and
IndexMetaData to disk when new ClusterState is received. All other
ClusterState fields are not persisted.
However, there are other parts of ClusterState that should be
persisted, namely:
version
term
lastCommittedConfiguration
lastAcceptedConfiguration
votingTombstones
version is changed frequently, other fields are not. We decided
to group term, lastCommittedConfiguration,
lastAcceptedConfiguration and votingTombstones into
CoordinationMetaData class and make CoordinationMetaData a field
inside MetaData.
MetaData.toXContent and MetaData.fromXContent should take care of
CoordinationMetaData.
version stays as a top level field in ClusterState and will be
persisted as part of Manifest in a follow-up commit.
Also MetaData.isGlobalStateEquals should be extended to include
coordinationMetaData in comparison.
This commit favors exposing getters, such as getTerm directly in
ClusterState to avoid massive code changes.
An example of CoordinationMetaState.toXContent:
{
"term": 1,
"last_committed_config": [
"TiIuBcbBtpuXyDDVHXeD",
"ZIAoVbkjjLPLUuYLaTkw"
],
"last_accepted_config": [
"OwkXbXZNOZPJqccdFHdz",

}
Move away from performing eager, fail-fast validation of mismatched
mapping to a lazy evaluation based on the fields actually used in the
query. This allows queries to run on the parts of the indices that
"work" which is not just convenient but also a necessity for large
mappings (like logging) where alignment is hard/impossible to achieve.

Creates the manage_token cluster privilege and adds it to the
kibana_system role. This is required if kibana were to use the token

Because kibana_system already has manage_saml this effectively
only adds the privilege to create tokens.
Introduce INTERVAL as a DataType

as well as the plurals of the units:
> INTERVAL 2 YEARS

Currently there is a common NPE in the IndexFollowingIT that does not

This commit checks that the metadata is not null before performing the
logic that depends on the metadata.
Zen2 is now feature-complete enough to run most ESIntegTestCase tests. The changes in this PR
are as follows:
- ClusterSettingsIT is adapted to not be Zen1 specific anymore (it was using Zen1 settings).
- Some of the integration tests require persistent storage of the cluster state, which is not fully
implemented yet (see #33958). These tests keep running with Zen1 for now but will be switched
over as soon as that is fully implemented.
- Some very few integration tests are not running yet with Zen2 for other reasons, depending on
some of the other open points in #32006.

RolloverAction will now periodically check the rollover conditions using
the Rollover API with the dry_run option as an AsyncWaitStep, then run

race condition issues in policies using RolloverAction.
Today, the bootstrapping of a Zen2 cluster is driven externally, requiring
something else to wait for discovery to converge and then to inject the initial

This change introduces the `ClusterBootstrapService` which brings the bootstrap
retry logic within each node and allows it to be controlled via an (unsafe)
node setting.

Kibana now uses the tasks API to manage automatic reindexing of the
.kibana index during upgrades.
The implementation of the tasks API requires that
1. the user executing the task can create & write to the ".tasks" index
2. the user checking on the status of the task can read (Get) the
relevant document from the ".tasks" index
Response classes in Elasticsearch (and xpack) only need to implement ToXContent, which is needed to print their output put in the REST layer and return the response in json (or others) format. On the other hand, response classes that are added to the high-level REST client, need to do the opposite: parse xcontent and create a new object based on that.
This commit removes the parsing code from the XPackInfoResponse server variant, and the toXContent portion from the corresponding client variant. It also removes a client specific test class that looks redundant now that we have a single test class for both classes.
This pull request replaces some blocks of code that must be run once
and that are currently based on AtomicBoolean by the convient RunOnce
class added in #35489.
