A persistent action is a transport-like action that is using the cluster state instead of transport to start tasks. This allows persistent tasks to survive restart of executing nodes. A persistent action can be implemented by extending TransportPersistentAction. TransportPersistentAction will start the task by using PersistentActionService, which controls persistent tasks lifecycle. See TestPersistentActionPlugin for an example implementing a persistent action.

This used to be 60 seconds, dating back to the days when the controller
had to be started manually after starting Elasticsearch. However, now
Elasticsearch starts it automatically it should already be running when
we try to connect, so the timeout can be much lower. It just needs to
be long enough to give the C++ process time to create its named pipes.
2 seconds seems reasonable, and matches what we use for autodetect and
normalize.

This contains the Painless-based DomainSplit function, generated static maps and basic tests. Due to cross-module complications, the tests are run by executing searches with script_fields and checking the response
Original commit: elastic/x-pack-elasticsearch@c6c2942e01
When source fields are not required, stored_fields can be disabled.
This can make the query faster as no stored fields have to be
decompressed. Note that this means no metadata (_id, _index, _type, etc.)
will be returned.

Even though a search response may return a 200 status code, things could
still have gone wrong. A search response may report shard failures.
The datafeed extractors should check for that and report an extraction
error accordingly.

* Handle manual aggregations in datafeeds
Adds a DataExtractor implementation that runs aggregated searches.
The manual aggregations supported have the following limitations:
- each aggregation can hava 0 or 1 sub-aggregations
- the top aggregation has to be a histogram
- sub-aggregations have to be either terms aggregations or single value
metric aggregations.
The response is converted into flat JSON documents that contain only the
fields of interest and can be parsed without additional context from our
JSON parser. The fields in the JSON documents correspond to the names of the aggregations.

The new constructor takes an Environment object. This is needed for migration to X-Pack since the environment instance is built by the XPackPlugin and then passed into the feature plugins.

Most transforms will be replaced with Painless scripts.
The exception is the DateTransform, whose functionality is now simplified
to what existed before the other transforms were added.
The SINGLE_LINE format relied on transforms to extract fields, so has also
been removed, but this is reasonable as it strays into Logstash territory.

The build would fail certain task (e.g. `gradle tasks` and `gradle :prelert-legacy:test`) if run from the elasticsearch root directory because the project references in the build were not abolute project paths from the root, they were relative to the `prelert-legacy` project. This change fixes the references so they are all absolute project paths.

This matches the way tests that need to run without an Elasticsearch
bootstrap are run in core Elasticsearch. This should make merging to
x-pack easier.
Note that the no bootstrap tests now run after the integration tests, but
this doesn't really matter.

The bulk request needed resetting after it was executed otherwise stale documents are persisted repeatedly after they have been updated causing a versioning error

* Gets build to use elasticsearch-extras
Also adds ci script for building repo on CI servers
To use this change you need to:
1. Clone elasticsearch: `git@github.com:elastic/elasticsearch.git`
2. create a directory at the same level as elasticsearch called `elasticsearch-extra`
3. Clone this repository into the `elasticsearch-extra` directory
4. Run `gradle build` from the `elasticsearch-extra/prelert-legacy` directory or run `gradle :prelert-legacy:build` from the `elasticsearch directory
* Adds USE_SSH option to ci script
* iter

The job open api starts a task and ties that AutodetectCommunicator.
The job close api is a sugar api, that uses the list and cancel task api to close a AutodetectCommunicator instance.
The flush job and post data api redirect to the node holding the job task and then delegate the flush or data to the AutodetectCommunicator instance.
Also:
* Added basic multi node cluster test.
* Fixed cluster state diffs bugs, forgot to mark ml metadata diffs as named writeable.
* Moved waiting for open job logic into OpenJobAction.TransportAction and moved the logic that was original there to a new action named InternalOpenJobAction.

* removes upload pack task from build
This is preventing us from being an elasticsearch-extra project and we cannot have this task when we move to x-pack. Once we are in X-Pack the unified build will be uploading the final artifact so for now we will change the CI build to add a build step to upload the pack artifact.
* Removes OS specific stuff from the build
the CPP_LOCAL_DIST will now look for any `ml-cpp` artifacts for the same version in the specified directory.
* review corrections

This commit contains some more of the endpoint changes Sophie and Steve
agreed with Clint:
1. get_jobs_stats renamed to get_job_stats
2. Revert snapshot must now be done using an ID - other options removed
3. Renamed "categorydefinitions" to "categories" in endpoints
4. get_jobs now has an implicit _all if no job ID/wildcard is specified
5. There is an option to retrieve a specific model snapshot by ID in
get_model_snapshots

This change prepares for elastic/elasticsearch/elastic/elasticsearch#22575, where we don't have ClusterService available in rest actions.
Original commit: elastic/x-pack-elasticsearch@87658c7fe8
This commit performs the following improvements:
- the time field is always requested as doc_value. This makes
specifying a time format for scheduled jobs unnecessary.
- adds DataDescription as a param to the PostDataAction. When set,
it overrides the job's DataDescription. This allows the scheduler to
override the job's DataDescription since it knows the data format (JSON)
and the time format (epoch_ms). This is not exposed in the REST API to
discourage users from using it.
- by default, data extractor search now requests doc_values for analysis fields. This is
expected to result in increased performance.
- a `_source` field is added to the scheduler config. This needs to be
set to true when one or more of the analysis fields do not have
doc_values.
- the ELASTICSEARCH data format is removed as is now redundant.
- fixes the usage of `script_fields`. Previously, setting
`script_fields` would result to none of the source to be returned. Thus,
is the analysis fields were a mixture of script and non-script fields it
would not work.
- ensures nested fields are handled properly
