[ML] Improve response format of data frame stats endpoint (#44743)
This change adjusts the data frame transforms stats
endpoint to return a structure that is easier to
understand.

This is a breaking change for clients of the data frame
transforms stats endpoint, but the feature is in beta so
stability is not guaranteed.

Backport of #44350

Ioannis Kakavas 3714cb63da Allow parsing the value of java.version sysprop (#44017)
We often start testing with early access versions of new Java
versions and this have caused minor issues in our tests
(i.e. #43141) because the version string that the JVM reports
cannot be parsed as it ends with the string -ea.

This commit changes how we parse and compare Java versions to
allow correct parsing and comparison of the output of java.version
system property that might include an additional alphanumeric
part after the version numbers
 (see [JEP 223[(https://openjdk.java.net/jeps/223)). In short it 
handles a version number part, like before, but additionally a 
PRE part that matches ([a-zA-Z0-9]+).

It also changes a number of tests that would attempt to parse
java.specification.version in order to get the full version
of Java. java.specification.version only contains the major
version and is thus inappropriate when trying to compare against
a version that might contain a minor, patch or an early access
part. We know parse java.version that can be consistently
parsed.

David Roberts 6d27eec30f [ML-DataFrame] Use lenient expand open in data frame searches (#44633)
Since #44344 we use IndicesOptions.LENIENT_EXPAND_OPEN
when deciding which indices to include in checkpoint
calculation. This change uses the same option when
deciding which indices to search for data and which
indices to get mappings from, otherwise there is a
potential mismatch between the checkpoint details and
what is searched elsewhere.

Introduce test issue logging (#44477)
Today we have an annotation for controlling logging levels in
tests. This annotation serves two purposes, one is to control the
logging level used in tests, when such control is needed to impact and
assert the behavior of loggers in tests. The other use is when a test is
failing and additional logging is needed. This commit separates these
two concerns into separate annotations.

The primary motivation for this is that we have a history of leaving
behind the annotation for the purpose of investigating test failures
long after the test failure is resolved. The accumulation of these stale
logging annotations has led to excessive disk consumption. Having
recently cleaned this up, we would like to avoid falling into this state
again. To do this, we are adding a link to the test failure under
investigation to the annotation when used for the purpose of
investigating test failures. We will add tooling to inspect these
annotations, in the same way that we have tooling on awaits fix
annotations. This will enable us to report on the use of these
annotations, and report when stale uses of the annotation exist.

Isolate nio channel registered from channel active (#44388)
Registering a channel with a selector is a required operation for the
channel to be handled properly. Currently, we mix the registeration with
other setup operations (ip filtering, SSL initiation, etc). However, a
fail to register is fatal. This PR modifies how registeration occurs to
immediately close the channel if it fails.

There are still two clear loopholes for how a user can interact with a
channel even if registration fails. 1. through the exception handler.
2. through the channel accepted callback. These can perhaps be improved
in the future. For now, this PR prevents writes from proceeding if the
channel is not registered.

Avoid stack overflow in auto-follow coordinator (#44421)
This commit avoids a situation where we might stack overflow in the
auto-follower coordinator. In the face of repeated failures to get the
remote cluster state, we would previously be called back on the same
thread and then recurse to try again. If this failure persists, the
repeated callbacks on the same thread would lead to a stack
overflow. The repeated failures can occur, for example, if the connect
queue is full when we attempt to make a connection to the remote
cluster. This commit avoids this by truncating the call stack if we are
called back on the same thread as the initial request was made on.

[7.x] Add Snapshot Lifecycle Management (#44382)
* Add Snapshot Lifecycle Management (#43934)

* Add SnapshotLifecycleService and related CRUD APIs

This commit adds `SnapshotLifecycleService` as a new service under the ilm
plugin. This service handles snapshot lifecycle policies by scheduling based on
the policies defined schedule.

This also includes the get, put, and delete APIs for these policies

Relates to #38461

* Make scheduledJobIds return an immutable set

* Use Object.equals for SnapshotLifecyclePolicy

* Remove unneeded TODO

* Implement ToXContentFragment on SnapshotLifecyclePolicyItem

* Copy contents of the scheduledJobIds

* Handle snapshot lifecycle policy updates and deletions (#40062)

(Note this is a PR against the `snapshot-lifecycle-management` feature branch)

This adds logic to `SnapshotLifecycleService` to handle updates and deletes for
snapshot policies. Policies with incremented versions have the old policy
cancelled and the new one scheduled. Deleted policies have their schedules
cancelled when they are no longer present in the cluster state metadata.

Relates to #38461

* Take a snapshot for the policy when the SLM policy is triggered (#40383)

(This is a PR for the `snapshot-lifecycle-management` branch)

This commit fills in `SnapshotLifecycleTask` to actually perform the
snapshotting when the policy is triggered. Currently there is no handling of the
results (other than logging) as that will be added in subsequent work.

This also adds unit tests and an integration test that schedules a policy and
ensures that a snapshot is correctly taken.

Relates to #38461

* Record most recent snapshot policy success/failure (#40619)

Keeping a record of the results of the successes and failures will aid
troubleshooting of policies and make users more confident that their
snapshots are being taken as expected.

This is the first step toward writing history in a more permanent
fashion.

* Validate snapshot lifecycle policies (#40654)

(This is a PR against the `snapshot-lifecycle-management` branch)

With the commit, we now validate the content of snapshot lifecycle policies when
the policy is being created or updated. This checks for the validity of the id,
name, schedule, and repository. Additionally, cluster state is checked to ensure
that the repository exists prior to the lifecycle being added to the cluster
state.

Part of #38461

* Hook SLM into ILM's start and stop APIs (#40871)

(This pull request is for the `snapshot-lifecycle-management` branch)

This change allows the existing `/_ilm/stop` and `/_ilm/start` APIs to also
manage snapshot lifecycle scheduling. When ILM is stopped all scheduled jobs are
cancelled.

Relates to #38461

* Add tests for SnapshotLifecyclePolicyItem (#40912)

Adds serialization tests for SnapshotLifecyclePolicyItem.

* Fix improper import in build.gradle after master merge

* Add human readable version of modified date for snapshot lifecycle policy (#41035)

* Add human readable version of modified date for snapshot lifecycle policy

This small change changes it from:

```
...
"modified_date": 1554843903242,
...
```

To

```
...
"modified_date" : "2019-04-09T21:05:03.242Z",
"modified_date_millis" : 1554843903242,
...
```

Including the `"modified_date"` field when the `?human` field is used.

Relates to #38461

* Fix test

* Add API to execute SLM policy on demand (#41038)

This commit adds the ability to perform a snapshot on demand for a policy. This
can be useful to take a snapshot immediately prior to performing some sort of
maintenance.

```json
PUT /_ilm/snapshot/<policy>/_execute
```

And it returns the response with the generated snapshot name:

```json
{
  "snapshot_name" : "production-snap-2019.04.09-rfyv3j9qreixkdbnfuw0ug"
}
```

Note that this does not allow waiting for the snapshot, and the snapshot could
still fail. It *does* record this information into the cluster state similar to
a regularly trigged SLM job.

Relates to #38461

* Add next_execution to SLM policy metadata (#41221)

* Add next_execution to SLM policy metadata

This adds the next time a snapshot lifecycle policy will be executed when
retriving a policy's metadata, for example:

* Fix and enhance tests

* Figured out how to Cron

* Change SLM endpoint from /_ilm/* to /_slm/* (#41320)

This commit changes the endpoint for snapshot lifecycle management from:

```
GET /_ilm/snapshot/<policy>
```

to:

```
GET /_slm/policy/<policy>
```

It mimics the ILM path only using `slm` instead of `ilm`.

* Add initial documentation for SLM (#41510)

* Add initial documentation for SLM

This adds the initial documentation for snapshot lifecycle management.

It also includes the REST spec API json files since they're sort of
documentation.

* Add `manage_slm` and `read_slm` roles (#41607)

* Add `manage_slm` and `read_slm` roles

This adds two more built in roles -

`manage_slm` which has permission to perform any of the SLM actions, as well as
stopping, starting, and retrieving the operation status of ILM.

`read_slm` which has permission to retrieve snapshot lifecycle policies as well
as retrieving the operation status of ILM.

* Add execute to the test

* Fix ilm -> slm typo in test

* Record SLM history into an index (#41707)

It is useful to have a record of the actions that Snapshot Lifecycle
Management takes, especially for the purposes of alerting when a
snapshot fails or has not been taken successfully for a certain amount of
time.

This adds the infrastructure to record SLM actions into an index that
can be queried at leisure, along with a lifecycle policy so that this
history does not grow without bound.

Additionally,
SLM automatically setting up an index + lifecycle policy leads to
`index_lifecycle` custom metadata in the cluster state, which some of
the ML tests don't know how to deal with due to setting up custom
`NamedXContentRegistry`s.  Watcher would cause the same problem, but it
is already disabled (for the same reason).

*  Add Getting Started Guide for SLM  (#42878)

This commit adds a basic Getting Started Guide for SLM.

* Include SLM policy name in Snapshot metadata (#43132)

Keep track of which SLM policy in the metadata field of the Snapshots
taken by SLM. This allows users to more easily understand where the
snapshot came from, and will enable future SLM features such as
retention policies.
