* [ML] ML Model Inference Ingest Processor (#49052)

* [ML][Inference] adds lazy model loader and inference (#47410)

This adds a couple of things:

- A model loader service that is accessible via transport calls. This service will load in models and cache them. They will stay loaded until a processor no longer references them
- A Model class and its first sub-class LocalModel. Used to cache model information and run inference.
- Transport action and handler for requests to infer against a local model

[7.x][ML] Prevent fetching multi-field from source (#48770) (#48797)
Aggregatable mutli-fields are at the moment wrongly mapped
as normal doc_value fields and thus they support fetching from
source. However, they do not exist in the source. This results
to failure to extract such fields.

This commit fixes this bug. While a fix could be worked out
on top of the existing code, it is evident the extraction logic
has become difficult to understand and maintain. As we also
want to deduplicate multi-fields for data frame analytics,
it seemed appropriate to refactor the code to simplify and
better handle the extraction of multi-fields.

[7.x][ML] Always refresh dest index before starting analytics process (#48090) (#48196)
If a job stops right after reindexing is finished but before
we refresh the destination index, we don't refresh at all.
If the job is started again right after, it jumps into the analyzing state.
However, the data is still not searchable.
This is why we were seeing test failures that we start the process
expecting X rows (where X is lower than the expected number of docs)
and we end up getting X+.

We fix this by moving the refresh of the dest index right before
we start the process so it always ensures the data is searchable.

David Roberts d9c7e3847e [TEST] Don't assert order of data frame analytics audit messages (#48065)
Audit messages are stored with millisecond timestamps. If two

This PR changes the assertion on audit messages in the native
data frame analytics tests to assert that the expected audit
messages exist in any order.

[ML][7.x] Add lazy assignment job config option (#47993)
This change adds:

- A new option, allow_lazy_open, to anomaly detection jobs
- A new option, allow_lazy_start, to data frame analytics jobs

Both work in the same way: they allow a job to be
opened/started even if no ML node exists that can
accommodate the job immediately. In this situation
the job waits in the opening/starting state until ML
node capacity is available. (The starting state for data
frame analytics jobs is new in this change.)

Additionally, the ML nightly maintenance tasks now
creates audit warnings for ML jobs that are unassigned.
This means that jobs that cannot be assigned to an ML
node for a very long time will show a yellow warning
triangle in the UI.

A final change is that it is now possible to close a job
that is not assigned to a node without using force.
This is because previously jobs that were open but
not assigned to a node were an aberration, whereas
after this change they'll be relatively common.

[7.x][ML] Restore analytics state if available (#47128) (#47393)
This commit restores the model state if available in data
frame analytics jobs.

In addition, this changes the start API so that a stopped job
can be restarted. As we now store the progress in the state index
when the task is stopped, we can use it to determine what state
the job was in when it got stopped.

Note that in order to be able to distinguish between a job
that runs for the first time and another that is restarting,
we ensure reindexing progress is reported to be at least 1
for a running task.

Convert most awaitBusy calls to assertBusy (#45794) (#47112)
Backport of #45794 to 7.x. Convert most `awaitBusy` calls to
`assertBusy`, and use asserts where possible. Follows on from #28548 by
@liketic.

There were a small number of places where it didn't make sense to me to
call `assertBusy`, so I kept the existing calls but renamed the method to
`waitUntil`. This was partly to better reflect its usage, and partly so
that anyone trying to add a new call to awaitBusy wouldn't be able to find
it.

I also didn't change the usage in `TransportStopRollupAction` as the
comments state that the local awaitBusy method is a temporary
copy-and-paste.

Other changes:

  * Rework `waitForDocs` to scale its timeout. Instead of calling
    `assertBusy` in a loop, work out a reasonable overall timeout and await
    just once.
  * Some tests failed after switching to `assertBusy` and had to be fixed.
  * Correct the expect templates in AbstractUpgradeTestCase.  The ES
    Security team confirmed that they don't use templates any more, so
    remove this from the expected templates. Also rewrite how the setup
    code checks for templates, in order to give more information.
  * Remove an expected ML template from XPackRestTestConstants The ML team
    advised that the ML tests shouldn't be waiting for any
    `.ml-notifications*` templates, since such checks should happen in the
    production code instead.
  * Also rework the template checking code in `XPackRestTestHelper` to give
    more helpful failure messages.
  * Fix issue in `DataFrameSurvivesUpgradeIT` when upgrading from < 7.4

David Roberts 77cc6d5bad [TEST] Work around _cat/indices bug with security enabled (#47160)
When the ML native multi-node tests use _cat/indices/_all
and the request goes to a non-master node, _all is
translated to a list of concrete indices by the authz layer
on the coordinating node before the request is forwarded
to the master node. Then it is possible for the master
node to return an index_not_found_exception if one of
the concrete indices that was expanded on the
coordinating node has been deleted in the meantime.
(#47159 has been opened to track the underlying problem.)

It has been observed that the index that gets deleted when
the problem affects the ML native multi-node tests is
always the ML notifications index. The tests that fail are
only interested in the presence or absense of ML results
indices. Therefore the workaround is to only _cat indices
that match the ML results index pattern.

[7.x][ML] MlMemoryTracker should ignore analytics tasks without config (#46789) (#46811)
It is possible for a running analytics job that its config is removed
from the '.ml-config' index (perhaps the user deleted the entire index,
etc.). In that case the task remains without a matching config. I have
raised #46781 to discuss how to deal with this issue.

This commit focuses on `MlMemoryTracker` and changes it so that when
we get the configs for the running tasks we leniently ignore missing ones.
This at least means memory tracking will keep working for other jobs
if one or more are missing.

In addition, this commit makes the cleanup code for native analytics
tests more robust by explicitly stopping all jobs and force-stopping
if an error occurs. This helps so that a single failing test does
not cause other tests fail due to pending tasks.

[7.x][ML] Add option to regression to randomize training set (#45969) (#46017)
Adds a parameter `training_percent` to regression. The default
value is `100`. When the parameter is set to a value less than `100`,
from the rows that can be used for training (ie. those that have a
value for the dependent variable) we randomly choose whether to actually
use for training. This enables splitting the data into a training set and
the rest, usually called testing, validation or holdout set, which allows
for validating the model on data that have not been used for training.

Technically, the analytics process considers as training the data that
have a value for the dependent variable. Thus, when we decide a training
row is not going to be used for training, we simply clear the row's
dependent variable.

[7.x][ML] Improve progress reportings for DF analytics (#45856) (#45910)
Previously, the stats API reports a progress percentage
for DF analytics tasks that are running and are in the
`reindexing` or `analyzing` state.

This means that when the task is `stopped` there is no progress
reported. Thus, one cannot distinguish between a task that never
run to one that completed.

In addition, there are blind spots in the progress reporting.
In particular, we do not account for when data is loaded into the
process. We also do not account for when results are written.

This commit addresses the above issues. It changes progress
to being a list of objects, each one describing the phase
and its progress as a percentage. We currently have 4 phases:
reindexing, loading_data, analyzing, writing_results.

When the task stops, progress is persisted as a document in the
state index. The stats API now reports progress from in-memory
if the task is running, or returns the persisted document
(if there is one).

Regression analysis support missing fields. Even more, it is expected
that the dependent variable has missing fields to the part of the
data frame that is not for training.

This commit allows to declare that an analysis supports missing values.
For such analysis, rows with missing values are not skipped. Instead,
they are written as normal with empty strings used for the missing values.

This also contains a fix to the integration test.

[7.x][ML] Check dest index is empty when starting DF analytics (#45094) (#45112)
If one tries to start a DF analytics job that has already run,
the result will be that the task will fail after reindexing the
dest index from the source index. The results of the prior run
will be gone and the task state is not properly set to failed
with the failure reason.

This commit improves the behavior in this scenario. First, we
set the task state to `failed` in a set of failures that were
missed. Second, a validation is added that if the destination
index exists, it must be empty.

[ML] Outlier detection should only fetch docs that have the analyzed … (#44944) (#44959)
As data frame rows with missing values for analyzed fields are skipped,
we can be more efficient by including a query that only picks documents
that have values for all analyzed fields. Besides improving the number

of how many rows we need which reduces the memory requirements.

This also adds an integration test that runs outlier detection on data

* This also introduces a minor limitation: aliases type of fields that
are NOT part of a tree of sub-fields will not be able to be retrieved
anymore. field_caps API doesn't shed any light into a field being an
alias or not and at _source parsing time there is no way to know if a
root field is an alias or not. Fields of the type "a.b.c.alias" can be
extracted from docvalue_fields, only if the field they point to can be
extracted from docvalue_fields. Also, not all fields in a hierarchy of
fields can be evaluated to being an alias.

[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:

```json

    "version" : 1,
    "modified_date" : "2019-04-15T21:16:21.865Z",

        "ignore_unavailable" : true,
        "include_global_state" : false
      }
    },
    "next_execution" : "2019-04-15T21:16:30.000Z",
    "next_execution_millis" : 1555362990000
  },
  "other" : {
    "version" : 1,
    "modified_date" : "2019-04-15T21:12:19.959Z",
    "modified_date_millis" : 1555362739959,
    "policy" : {

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

Relates to #38461

* 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).

it attempts a best-effort approach to merge the mappings assuming

To allow users creating custom mappings for special use cases,
the destination index is now allowed to exist before the analytics
job runs. In addition, settings are no longer copied except for
the `index.number_of_shards` and `index.number_of_replicas`.

[7.x][ML] Machine learning data frame analytics (#43544) (#43592)
This merges the initial work that adds a framework for performing
machine learning analytics on data frames. The feature is currently experimental
and requires a platinum license. Note that the original commits can be
found in the `feature-ml-data-frame-analytics` branch.

A new set of APIs is added which allows the creation of data frame analytics
jobs. Configuration allows specifying different types of analysis to be performed
on a data frame. At first there is support for outlier detection.

The APIs are:

- PUT _ml/data_frame/analysis/{id}
- GET _ml/data_frame/analysis/{id}
- GET _ml/data_frame/analysis/{id}/_stats
- POST _ml/data_frame/analysis/{id}/_start
- POST _ml/data_frame/analysis/{id}/_stop
- DELETE _ml/data_frame/analysis/{id}

When a data frame analytics job is started a persistent task is created and started.
The main steps of the task are:

1. reindex the source index into the dest index
2. analyze the data through the data_frame_analyzer c++ process
3. merge the results of the process back into the destination index

In addition, an evaluation API is added which packages commonly used metrics
that provide evaluation of various analysis:

- POST _ml/data_frame/_evaluate

[7.x Backport] Force selection of calendar or fixed intervals (#41906)
The date_histogram accepts an interval which can be either a calendar
interval (DST-aware, leap seconds, arbitrary length of months, etc) or
fixed interval (strict multiples of SI units). Unfortunately this is inferred
by first trying to parse as a calendar interval, then falling back to fixed
if that fails.

This leads to confusing arrangement where `1d` == calendar, but
`2d` == fixed.  And if you want a day of fixed time, you have to
specify `24h` (e.g. the next smallest unit).  This arrangement is very
error-prone for users.

This PR adds `calendar_interval` and `fixed_interval` parameters to any
code that uses intervals (date_histogram, rollup, composite, datafeed, etc).
Calendar only accepts calendar intervals, fixed accepts any combination of
units (meaning `1d` can be used to specify `24h` in fixed time), and both
are mutually exclusive.

The old interval behavior is deprecated and will throw a deprecation warning.
It is also mutually exclusive with the two new parameters. In the future the
old dual-purpose interval will be removed.

The change applies to both REST and java clients.

The problem here was that `DatafeedJob` was updating the last end time searched
based on the `now` even though when there are aggregations, the extactor will
only search up to the floor of `now` against the histogram interval.
This commit fixes the issue by using the end time as calculated by the extractor.

It also adds an integration test that uses aggregations. This test would fail
