On second thought, this check does not seem to be adding value.
We can test that the phases are as we expect them for each analysis
by adding yaml tests. Those would fail if we introduce new phases
from c++ accidentally or without coordination. This would achieve
the same thing. At the same time we would not have to comment out
this code each time a new phase is introduced. Instead we can just
temporarily mute those yaml tests. Note I will add those tests
right after the imminent new phases are added to the c++ side.

While it is good to not be lenient when attempting to guess the file format, it is frustrating to users when they KNOW it is CSV but there are a few ill-formatted rows in the file (via some entry error, etc.).
This commit allows for up to 10% of sample rows to be considered "bad". These rows are effectively ignored while guessing the format.
This percentage of "allows bad rows" is only applied when the user has specified delimited formatting options. As the structure finder needs some guidance on what a "bad row" actually means.

Backports #55681 to 7.x
We were previously checking at least one supported field existed
when the _explain API was called. However, in the case of analyses
with required fields (e.g. regression) we were not accounting that
the dependent variable is not a feature and thus if the source index
only contains the dependent variable field there are no features to
train a model on.
This commit adds a validation that at least one feature is available
for analysis. Note that we also move that validation away from
`ExtractedFieldsDetector` and the _explain API and straight into
the _start API. The reason for doing this is to allow the user to use
the _explain API in order to understand why they would be seeing an
error like this one.
For example, the user might be using an index that has fields but
they are of unsupported types. If they start the job and get
an error that there are no features, they will wonder why that is.
Calling the _explain API will show them that all their fields are
unsupported. If the _explain API was failing instead, there would
be no way for the user to understand why all those fields are
ignored.

This replaces a reference to the result of partially reducing
aggregations that async search keeps with a reference to the serialized
form of the result of the partial reduction which we need to keep
anyway.
This has no practical impact on users since frozen indices are the only
throttled indices today. However this has an impact on upcoming features
that would use search throttling.
Filtering out throttled indices made sense a couple years ago, but as
we're now improving support for slow requests with `_async_search` and
exploring ways to reduce storage costs, this feature has most likely
become a trap, that we'd like to not have with upcoming features that
would use search throttling.

Today when prewarming a searchable snapshot we use the `SparseFileTracker` to
lock each (part of a) snapshotted blob, blocking any other readers from
accessing this data until the whole part is available.
This commit changes this strategy: instead we optimistically start to download
the blob without any locking, and then lock much smaller ranges after each
individual `read()` call. This may mean that some bytes are downloaded twice,
but reduces the time that other readers may need to wait before the data they
need is available.
As a best-effort optimisation we try to request the smallest possible single
range of missing bytes in the part by first checking how many of the initial
and terminal bytes of the part are already present in cache. In particular if
the part is already fully cached before prewarming then this check means we
skip the part entirely.
Currently there is a clear mechanism to stub sending a request through
the transport. However, this is limited to testing exceptions on the
sender side. This commit reworks our transport related testing
infrastructure to allow stubbing request handling on the receiving side.
Adding to #55659, we missed another way we could set the task to
failed due to task cancellation. CI revealed that we might also
get a `SearchPhaseExecutionException` whose cause is a
`TaskCancelledException`. That exception is not wrapped so
unwrapping it will not return the underlying `TaskCancelledException`.
Thus to be complete in catching this, we also need to check the
error's cause.

This is a continuation from #55580.
Now that we're parsing phase progresses from the analytics process
we change `ProgressTracker` to allow for custom phases between
the `loading_data` and `writing_results` phases. Each `DataFrameAnalysis`

This commit sets things in place for the analytics process to start
reporting different phases per analysis type. However, this is
still preserving existing behaviour as all analyses currently
declare a single `analyzing` phase.

This change adds validation when running the users tool so that
if Elasticsearch is expected to run in a JVM that is configured to
be in FIPS 140 mode and the password hashing algorithm is not
compliant, we would throw an error.
Users tool uses the configuration from the node and this validation
would also happen upon node startup but users might be added in the
file realm before the node is started and we would have the
opportunity to notify the user of this misconfiguration.
The changes in #55544 make this much less probable to happen in 8
since the default algorithm will be compliant but this change can
act as a fallback in anycase and makes for a better user experience.
Our handling for concurrent refresh of access tokens suffered from
a race condition where:
1. Thread A has just finished with updating the existing token
document, but hasn't stored the new tokens in a new document
yet
2. Thread B attempts to refresh the same token and since the
original token document is marked as refreshed, it decrypts and
gets the new access token and refresh token and returns that to
the caller of the API.
3. The caller attempts to use the newly refreshed access token
immediately and gets an authentication error since thread A still
hasn't finished writing the document.
This commit changes the behavior so that Thread B, would first try
to do a Get request for the token document where it expects that
the access token it decrypted is stored(with exponential backoff )
and will not respond until it can verify that it reads it in the
tokens index. That ensures that we only ever return tokens in a
response if they are already valid and can be used immediately
It also adjusts TokenAuthIntegTests
to test authenticating with the tokens each thread receives,
which would fail without the fix.

This commit refactors all spatial Field Mappers to a common
AbstractGeometryFieldMapper that implements shared parameter functionality
(e.g., ignore_malformed, ignore_z_value) and provides a common framework for
overriding type parsing, and building in xpack. Common shape functionality is
implemented in a new AbstractShapeGeometryFieldMapper that is reused and
overridden in GeoShapeFieldMapper, GeoShapeFieldMapperWithDocValues,
LegacyGeoShapeFieldMapper, and ShapeFieldMapper. This abstraction provides a
reusable foundation for adding new xpack features; such as coordinate reference
system support.
This commit removes some code duplication in the CCR non-compliance

This commit fixes reproducible test failures with the
SSLReloadDuringStartupIntegTests on the 7.x branch. The failures only
occur on 7.x due to the existence of the transport client and its usage
in our test infrastructure. This change removes the randomized usage of
transport clients when retrieving a client from a node in the internal
cluster. Transport clients do not support the reloading of files for
TLS configuration changes but if we build one from the nodes settings
and attempt to use it after the files have been changed, the client
will not know about the changes and the TLS connection will fail.

License state is currently made up of boolean methods that check whether
a particular feature is allowed by the current license state. Each new
feature must copy/past boiler plate code. While that has gotten easier
with utilities like isAllowedByLicense, this is still more cumbersome
than should be necessary. This commit adds a general purpose isAllowed
method which takes a new Feature enum, where each value of the enum
defines the minimum license mode and whether the license must be active
to be allowed. Only security features are converted in this PR, in order
to keep the commit size relatively small. The rest of the features will
be converted in a followup.
This adds a validation to VSParserHelper to ensure that a field or
script or both are specified by the user. This is technically
required today already, but throws an exception much deeper

The (de)serialization code of the async search response
cannot handle exceptions that extend ElasticsearchException (e.g. ScriptException).
This commit fixes this bug by serializing the error with the more generic
StreamInput#writeException.

While we were catching `TaskCancelledException` while we wait for
reindexing to complete, we missed the fact that this exception
may be wrapped in a multi-node cluster. This is the reason
we may still fail the task when stop is called while reindexing.
Some times we're lucky and the exception is thrown by the same
node that runs the job. Then the exception is not wrapped and
things work fine. But when that is not the case the exception is
wrapped, we fail to catch it, and set the task to failed.
The fix is to simply unwrap the exception when we check it it
is `TaskCancelledException`.

The CacheFile.fileLock() method is used to acquire a lock
on a cache file so that the file can't be deleted (or its file
handle closed) during the execution of a read or a write
operation.
Today this lock is obtained by first acquiring the eviction
lock (the write lock of the readwrite lock), then by checking
if the cache file is evicted and the file channel still open,
and finally by obtaining the file lock (the read lock of the
readwrite lock). Acquiring the read lock while the eviction
lock is held ensures that the cache file eviction cannot
start in the meanwhile. But eviction starts (and terminations)
also acquire the eviction lock; and this lock cannot be
obtained while a read lock is held (the write lock of a
readwrite lock is exclusive).
If we were acquiring a read lock and checking the eviction
flag and file channel existence while holding the read lock
we know that no eviction can start or finish until the
read lock is released.

Data frame analytics process currently reports progress as

parsing `phase_progress` from the process, an object that
contains the `phase` name plus the `progress_percent` for that
phase.

The ML info endpoint returns the max_model_memory_limit setting
if one is configured. However, it is still possible to create
a job that cannot run anywhere in the current cluster because
no node in the cluster has enough memory to accommodate it.
This change adds an extra piece of information,
limits.effective_max_model_memory_limit, to the ML info
response that returns the biggest model memory limit that could
be run in the current cluster assuming no other jobs were
running.
The idea is that the ML UI will be able to warn users who try to
create jobs with higher model memory limits that their jobs will
not be able to start unless they add a bigger ML node to their
cluster.

Adds a "node" field to the response from the following endpoints:
1. Open anomaly detection job
2. Start datafeed
3. Start data frame analytics job
If the job or datafeed is assigned to a node immediately then
this field will return the ID of that node.
In the case where a job or datafeed is opened or started lazily
the node field will contain an empty string. Clients that want
to test whether a job or datafeed was opened or started lazily
can therefore check for this.

uses the key encryption password as the password for the ephemeral

This change folds the removal of the in-progress snapshot entry
into setting the safe repository generation. Outside of removing
an unnecessary cluster state update, this also has the advantage
of removing a somewhat inconsistent cluster state where the safe
repository generation points at `RepositoryData` that contains a
finished snapshot while it is still in-progress in the cluster
state, making it easier to reason about the state machine of
upcoming concurrent snapshot operations.
Today a read-only engine requires a complete history of operations, in the
sense that its local checkpoint must equal its maximum sequence number. This is
a valid check for read-only engines that were obtained by closing an index
since closing an index waits for all in-flight operations to complete. However
a snapshot may not have this property if it was taken while indexing was
ongoing, but that's ok.
This commit weakens the check for a complete history to exclude the case of a
searchable snapshot.

This commit also fixes a bug that stops the garbage collection of saved responses if the async search index is deleted.
If more than 100 shard-follow tasks are trying to connect to the remote

on RejectedExecutionException.
`updateAndGet` could actually call the internal method more than once on contention.
If I read the JavaDocs, it says:
```* @param updateFunction a side-effect-free function```
So, it could be getting multiple updates on contention, thus having a race condition where stats are double counted.
To fix, I am going to use a `ReadWriteLock`. The `LongAdder` objects allows fast thread safe writes in high contention environments. These can be protected by the `ReadWriteLock::readLock`.
When stats are persisted, I need to call reset on all these adders. This is NOT thread safe if additions are taking place concurrently. So, I am going to protect with `ReadWriteLock::writeLock`.
This should prevent race conditions while allowing high (ish) throughput in the highly contention paths in inference.
I did some simple throughput tests and this change is not significantly slower and is simpler to grok (IMO).

This paves the data layer way so that exceptionally large models are partitioned across multiple documents.
This change means that nodes before 7.8.0 will not be able to use trained inference models created on nodes on or after 7.8.0.
I chose the definition document limit to be 100. This *SHOULD* be plenty for any large model. One of the largest models that I have created so far had the following stats:
~314MB of inflated JSON, ~66MB when compressed, ~177MB of heap.
With the chunking sizes of `16 * 1024 * 1024` its compressed string could be partitioned to 5 documents.
Supporting models 20 times this size (compressed) seems adequate for now.

This commit adds a new querystring parameter on the following APIs:
- Index
- Update
- Bulk
- Create Index
- Rollover
These APIs now support a `?prefer_v2_templates=true|false` flag. This flag changes the preference
creation to use either V2 index templates or V1 templates. This flag defaults to `false` and will be
changed to `true` for 8.0+ in subsequent work.
Additionally, setting this flag internally sets the `index.prefer_v2_templates` index-level setting.
This setting is used so that actions that automatically create a new index (things like rollover
initiated by ILM) will inherit the preference from the original index. This setting is dynamic so
that a transition from v1 to v2 templates can occur for long-running indices grouped by an alias
performing periodic rollover.
This also adds support for sending this parameter to the High Level Rest Client.

We don't really need `LinkedHashSet` here. We can assume that all the

This change reworks the loading and monitoring of files that are used
for the construction of SSLContexts so that updates to these files are
not lost if the updates occur during startup. Previously, the
SSLService would parse the settings, build the SSLConfiguration
objects, and construct the SSLContexts prior to the
SSLConfigurationReloader starting to monitor these files for changes.
This allowed for a small window where updates to these files may never
be observed until the node restarted.
To remove the potential miss of a change to these files, the code now
parses the settings and builds SSLConfiguration instances prior to the
construction of the SSLService. The files back the SSLConfiguration
instances are then registered for monitoring and finally the SSLService
is constructed from the previously parse SSLConfiguration instances. As
the SSLService is not constructed when the code starts monitoring the
files for changes, a CompleteableFuture is used to obtain a reference
to the SSLService; this allows for construction of the SSLService to
complete and ensures that we do not miss any file updates during the
construction of the SSLService.
While working on this change, the SSLConfigurationReloader was also
refactored to reflect how it is currently used. When the
SSLConfigurationReloader was originally written the files that it
monitored could change during runtime. This is no longer the case as
we stopped the monitoring of files that back dynamic SSLContext
instances. In order to support the ability for items to change during
runtime, the class made use of concurrent data structures. The use of
these concurrent datastructures has been removed.

Some aggregations, such as the Terms* family, will use an alternate
class to represent unmapped shard results (while the rest of the aggs
use the same object but with some form of "empty" or "nullish" values
to represent unmapped).
This was problematic with AbstractWireSerializingTestCase because it
expects the instanceReader to always match the original class. Instead,
we need to use the NamedWriteable version so that the registry
can be consulted for the proper deserialization reader.
Security features in the license state currently do a dynamic check on
whether security is enabled. This is because the license level can
change the default security enabled state. This commit splits out the
check on security being enabled, so that the combo method of security
enabled plus license allowed is no longer necessary.
We believe there's no longer a need to be able to disable basic-license
features completely using the "xpack.*.enabled" settings. If users don't
want to use those features, they simply don't need to use them. Having
such features always available lets us build more complex features that
assume basic-license features are present.
This commit deprecates settings of the form "xpack.*.enabled" for
basic-license features, excluding "security", which is a special case.
It also removes deprecated settings from integration tests and unit
tests where they're not directly relevant; e.g. monitoring and ILM are
no longer disabled in many integration tests.
* [ML] fix bugs with prediction field value settings (#55333)
This fixes two unreleased bugs:
1. Prediction value type of `number` might show unexpected classes
Analytics created models may have class labels like `1, 5, 10` (or some collection of discrete, whole numbers). These labels are passed to the inference model config in the `classification_labels` field.
When the predicted value format is `numeric` it should attempt to see if the classification labels are provided and are numeric. If so, use those. If not, use the underlying value.
2. When supplying an update overwrite, inference was losing the default prediction field value. This is because it was not copied over in the copy ctor in the ClassificationConfig.Builder class.

This fixes the long muted testHRDSplit. Some minor adjustments for modern day elasticsearch changes :).
The cause of the failure is that a new `by` field entering the model with an exceptionally high count does not cause an anomaly. We have since stopped combining the `rare` and `by` in this manner. New entries in a `by` field are not anomalous because we have no history on them yet.

When a anomaly jobs, datafeeds, and analytics tasks are stopped, they enter an ephemeral state called `STOPPING`.
If the node executing the task fails while this is occurring, they could be stuck in the limbo state of `STOPPING`. It is best to mark the tasks as completed if they get reassigned to a node.
Implement the use of scalar functions inside aggregate functions.
This allows for complex expressions inside aggregations, with or without

FROM test
GROUP BY b

Scalar functions are still not allowed for `KURTOSIS` and `SKEWNESS` as
this is currently not implemented on the ElasticSearch side.

The INCLUDE_DATA_STREAMS indices option controls whether data streams can be resolved in an api for both concrete names and wildcard expressions. If data streams cannot be resolved then a 400 error is returned indicating that data streams cannot be used.
In this pr, the INCLUDE_DATA_STREAMS indices option is enabled in the following APIs: search, msearch, refresh, index (op_type create only) and bulk (index requests with op type create only). In a subsequent later change, we will determine which other APIs need to be able to resolve data streams and enable the INCLUDE_DATA_STREAMS indices option for these APIs.
Whether an api resolve all backing indices of a data stream or the latest index of a data stream (write index) depends on the IndexNameExpressionResolver.Context.isResolveToWriteIndex().
If isResolveToWriteIndex() returns true then data streams resolve to the latest index (for example: index api) and otherwise a data stream resolves to all backing indices of a data stream (for example: search api).

- Introduces a new API (`getBareAggregatorRegistrar()`) which allows plugins to register aggregations against existing agg definitions defined in Core.
- This moves the histogram VSType over to XPack where it belongs. `getHistogramValues()` still remains as a Core concept
- Moves the histo-specific bits over to xpack (e.g. the actual aggregator logic). This requires extra boilerplate since we need to create a new "Analytics" Percentile/Rank aggregators to deal with the histo field. Doubly-so since percentiles/ranks are extra boiler-plate'y... should be much lighter for other aggs

Fix MINIMUM_SCALE, MAXIMUM_SCALE and SQL_DATETIME_SUB
ODBC metadata for the DATE & TIME data types.
Fixes: #41086
(cherry picked from commit c23677cd2955e25bb952c8e7ff8ca3151ee0df98)
We have some Dockerfiles that reference Ubuntu 19.04, which is not an LTS
version and has now appears to have been retired from the Ubuntu repositories.
Switch to 18.04, which is the current long-term support version. Also change a
usage of 16.04 to 18.04, for consistency.
This change adds the spec for the new REST APIs that we
introduce for the IDP and documentation for each of the APIs. The
documentation pages are intentionally not included in the API
reference so as to minimize unnecessary exposure.
supersedes: #53858
When retrieving the snapshots for a set of repos or deleting a single snapshot, it's possible for
the body of the `ActionListener`'s `onResponse` method to throw an Exception. In this case, the
`errHandler` passed in may not be executed, resulting in the `running` boolean not being reset back
to false.
This commit uses `ActionListener.wrap(...)` instead of creating a new ActionListener, which ensures
that if the `onResponse` fails in any way, the `onFailure` handler is still called.
Resolves#55217
Today we pass the `RepositoriesService` to the searchable snapshots plugin
during the initialization of the `RepositoryModule`, forcing the plugin to be a
`RepositoryPlugin` even though it does not implement any repositories.
After discussion we decided it best for now to pass this in via
`Plugin#createComponents` instead, pending some future work in which plugins
can depend on services more dynamically.
Added an integration test to validate behaviour of string scalars on top
of aggregate functions. The behaviour was fixed with #49570.
Relates to: #41597
(cherry picked from commit 35f964154850e3f02b6c7f9ca238da98ad83ebb3)
Simplify the code by removing the generic type from InferenceConfigUpdate which
meant wildcard types were used in many places. Instead check the class type is
appropriate where used.
This commit fixes our behavior regarding the responses we
return in various cases for the use of token related APIs.
More concretely:
- In the Get Token API with the `refresh` grant, when an invalid
(already deleted, malformed, unknown) refresh token is used in the
body of the request, we respond with `400` HTTP status code
and an `error_description` header with the message "could not
refresh the requested token".
Previously we would return erroneously return a `401` with "token
malformed" message.
- In the Invalidate Token API, when using an invalid (already
deleted, malformed, unknown) access or refresh token, we respond
with `404` and a body that shows that no tokens were invalidated:
```
{
"invalidated_tokens":0,
"previously_invalidated_tokens":0,
"error_count":0
}
```
The previous behavior would be to erroneously return
a `400` or `401` ( depending on the case ).
- In the Invalidate Token API, when the tokens index doesn't
exist or is closed, we return `400` because we assume this is
a user issue either because they tried to invalidate a token
when there is no tokens index yet ( i.e. no tokens have
been created yet or the tokens index has been deleted ) or the
index is closed.
- In the Invalidate Token API, when the tokens index is
unavailable, we return a `503` status code because
we want to signal to the caller of the API that the token they
tried to invalidate was not invalidated and we can't be sure
if it is still valid or not, and that they should try the request
again.
Resolves: #53323
When a datafeed transitions from lookback to real-time we request
that state is persisted from the autodetect process in the
background.
This PR adds a test to prove that for a categorization job the
state that is persisted includes the categorization state.
Without the fix from elastic/ml-cpp#1137 this test fails. After
that C++ fix is merged this test should pass.
Backport of #55243
After #54650 we catch `TaskCancelledException` when we wait for
reindexing to complete as it may be thrown. However, when that happens
we do not mark the task as completed. This results in the stop request
never returning and the failures we saw in #55068.
Closes#55068
Backport of #55286
Following elastic/ml-cpp#1135 there are now Linux binaries
for both x86_64 and aarch64. The code that finds the
correct binaries to ship with each distribution was
including both on every Linux distribution. This change
alters that logic to consider the architecture as well
as the operating system.
Also, there is no need to disable ML on aarch64 now that
we have the native binaries available. ML is still not
supported on aarch64, but the processes at least run up
and work at a superficial level.
Backport of #55256
The ResourceWatcherService enables watching of files for modifications
and deletions. During startup various consumers register the files that
should be watched by this service. There is behavior that might be
unexpected in that the service may not start polling until later in the
startup process due to the use of lifecycle states to control when the
service actually starts the jobs to monitor resources. This change
removes this unexpected behavior so that upon construction the service
has already registered its tasks to poll resources for changes. In
making this modification, the service no longer extends
AbstractLifecycleComponent and instead implements the Closeable
interface so that the polling jobs can be terminated when the service
is no longer required.

Backport of #54993
Today we indiscriminately serialize these independent of the version on
the stream, even though the other side might not understand a new
feature set usage that we have added. For example, if we add feature set
usage in 7.7 for EQL, in a mixed cluster context if a request is sent to
an old coordinating node, but the master is a new version, then it would
attempt to serialize the usage information for the new feature back to
the old coordinating node, who will blow up on the unrecognized named
writeable. This commit addresses this by making feature usage version
aware, and only serializing those that the other side would understand.
I've noticed that a lot of our tests are using deprecated static methods
from the Hamcrest matchers. While this is not a big deal in any
objective sense, it seems like a small good thing to reduce compilation
warnings and be ready for a new release of the matcher library if we
need to upgrade. I've also switched a few other methods in tests that
have drop-in replacements.
Currently forbidden apis accounts for 800+ tasks in the build. These
tasks are aggressively created by the plugin. In forbidden apis 3.0, we
will get task avoidance
(https://github.com/policeman-tools/forbidden-apis/pull/162), but we
need to ourselves use the same task avoidance mechanisms to not trigger
these task creations. This commit does that for our foribdden apis
usages, in preparation for upgrading to 3.0 when it is released.
Added testing of following on top of a closed index.
This could for instance be the old leader index in
cases where leader and follower clusters have been
swapped.
Upgrade to lucene 8.5.1 release that contains a bug fix for a bug that might introduce index corruption when deleting data from an index that was previously shrunk.
* [ML] adding prediction_field_type to inference config (#55128)
Data frame analytics dynamically determines the classification field type. This field type then dictates the encoded JSON that is written to Elasticsearch.
Inference needs to know about this field type so that it may provide the EXACT SAME predicted values as analytics.
Here is added a new field `prediction_field_type` which indicates the desired type. Options are: `string` (DEFAULT), `number`, `boolean` (where close_to(1.0) == true, false otherwise).
Analytics provides the default `prediction_field_type` when the model is created from the process.
We can be a little more efficient when aborting a snapshot. Since we know the new repository
data after finalizing the aborted snapshot when can pass it down to the snapshot completion listeners.
This way, we don't have to fork off to the snapshot threadpool to get the repository data when the listener completes and can directly submit the delete task with high priority straight from the cluster state thread.
Sets the default cache size for searchable snapshots to unlimited, which, for testing purposes,
is a better default than the 1GB that we currently have.
We implicitly only supported the prime256v1 ( aka secp256r1 )
curve for the EC keys we read as PEM files to be used in any
SSL Context. We would not fail when trying to read a key
pair using a different curve but we would silently assume
that it was using `secp256r1` which would lead to strange
TLS handshake issues if the curve was actually another one.
This commit fixes that behavior in that it
supports parsing EC keys that use any of the named curves
defined in rfc5915 and rfc5480 making no assumptions about
whether the security provider in use supports them (JDK8 and
higher support all the curves defined in rfc5480).
Prior to the change in #51631 indices were moved to the `TerminalPolicyStep` when their ILM actions
had completed. Once we switched ILM to stop in the last policy configured, these steps because
inaccessible from the policy's perspective. This meant that indices upgraded from ES prior to 7.7.0
could see the following error spammed in their logs every 10 minutes (by default) for every index in
this state:
```
[2020-04-14T15:52:23,764][ERROR][o.e.x.i.IndexLifecycleRunner] [midgar] current step [{"phase":"completed","action":"completed","name":"completed"}] for index [foo] with policy [full] is not recognized
```
This changes the runner to ignore these steps, which is what is desired anyway since the index is
already in the terminal phase.
This change ensures that internal client requests spawned by the
transform persistent task executor and that use the end user security
credentials, have the parent task id assigned. The objective here is
to permit auditing (as well as tracking for debugging purposes) of all
the end-user requests executed on its behalf by persistent tasks.
Because transform tasks already implements graceful shutdown of the
child tasks, this change does not interfere with that by opting out of
the persistent task cancellation of child tasks.

This commit refactors the `AuditTrail` to use the `TransportRequest` as a parameter
for all its audit methods, instead of the current `TransportMessage` super class.
The goal is to gain access to the `TransportRequest#parentTaskId` member,
so that it can be audited. The `parentTaskId` is used internally when spawning tasks
that handle transport requests; in this way tasks across nodes are related by the
same parent task.

Provides basic repository-level stats that will allow us to get some insight into how many
requests are actually being made by the underlying SDK. Currently only tracks GET and LIST
calls for S3 repositories. Most of the code is unfortunately boiler plate to add a new endpoint
that will help us better understand some of the low-level dynamics of searchable snapshots.
Fixes a couple of related failures in SearchableSnapshotsIntegTests.
Firstly, we were not correctly accounting for the case where the cache was so
small that some/all files were read directly; fixed this by only asserting that
the cache is definitely used if the corresponding node has a cache that's large
enough to hold the whole index.
Secondly, we were not permitting shards to be completely empty, which might be
the case (rarely) if there were not many documents indexed and the distribution
of IDs was a bit unlucky; fixed this by asserting that we get stats for at
least one file for the whole index, rather than for each shard separately.

This is a first cut at giving NodeInfo the ability to carry a flexible
list of heterogeneous info responses. The trick is to be able to
serialize and deserialize an arbitrary list of blocks of information. It
is convenient to be able to deserialize into usable Java objects so that
we can aggregate nodes stats for the cluster stats endpoint.
In order to provide a little bit of clarity about which objects can and
can't be used as info blocks, I've introduced a new interface called
"ReportingService."
I have removed the hard-coded getters (e.g., getOs()) in favor of a
flexible method that can return heterogeneous kinds of info blocks
(e.g., getInfo(OsInfo.class)). Taking a class as an argument removes the
need to cast in the client code.
