* Reject queries that act on nested fields or fields with nested field types in their hierarchy (#55721)
(cherry picked from commit 2a024461cd9da821112953d4c6e565ea622c678b)

Implements value_count and avg aggregations over Histogram fields as discussed in #53285
- value_count returns the sum of all counts array of the histograms
- avg computes a weighted average of the values array of the histogram by multiplying each value with its associated element in the counts array
Using optimistic locking, add the ability to run a repository state
update task with a consistent view of the current repository data.
Allows for a follow-up to remove the snapshot INIT state.
* Allow Deleting Multiple Snapshots at Once (#55474)
Adds deleting multiple snapshots in one go without significantly changing the mechanics of snapshot deletes otherwise.
This change does not yet allow mixing snapshot delete and abort. Abort is still only allowed for a single snapshot delete by exact name.
* Make xpack.monitoring.enabled setting a no-op
This commit turns xpack.monitoring.enabled into a no-op. Mostly, this involved
removing the setting from the setup for integration tests. Monitoring may
introduce some complexity for test setup and teardown, so we should keep an eye
out for turbulence and failures
* Docs for making deprecated setting a no-op
This commit converts the remaining isXXXAllowed methods to instead of
use isAllowed with a Feature value. There are a couple other methods
that are static, as well as some licensed features that check the
license directly, but those will be dealt with in other followups.
* Emit deprecation warning if multiple v1 templates match with a new index (#55558)
* Emit deprecation warning if multiple v1 templates match with a new index
* DEPRECATION_LOGGER rename
This commit includes a number of minor improvements around `DelayableWriteable`: javadocs were expanded and reworded, `get` was renamed to `expand` and `DelayableWriteable` no longer implements `Supplier`. Also a couple of methods are now private instead of package private.
This commit correctly sets the maxLinesPerRow in the CsvPreference for delimited files given the file structure finder settings.
Previously, it was silently ignored.
This refactors native integ tests to assert progress without
expecting explicit phases for analyses. We can test those with
yaml tests in a single place.

* Make xpack.ilm.enabled setting a no-op
* Add watcher setting to not use ILM
* Update documentation for no-op setting
* Remove NO_ILM ml index templates
* Remove unneeded setting from test setup
* Inline variable definitions for ML templates
* Use identical parameter names in templates
* New ILM/watcher setting falls back to old setting
* Add fallback unit test for watcher/ilm setting
Fixes test by exposing the method ModelLoadingService::addModelLoadedListener()
so that the test class can be notified when a model is loaded which happens in
a background thread
implement throttling in async-indexer used by rollup and transform. The added
docs_per_second parameter is used to calculate a delay before the next
search request is send. With re-throttle its possible to change the parameter
at runtime. When stopping a running job, its ensured that despite throttling
the indexer stops in reasonable time. This change contains the groundwork, but
does not expose the new functionality.

We were creating PemKeyConfig objects using different private
keys but always using testnode.crt certificate that uses the
RSA public key. The PemKeyConfig was built but we would
then later fail to handle SSL connections during the TLS
handshake eitherway.
This became obvious in FIPS tests where the consistency
checks that FIPS 140 mandates kick in and failed early
becausethe private key was of different type than the
public key
Anonymous roles resolution and user role deduplication are now performed during authentication instead of authorization. The change ensures:
* If anonymous access is enabled, user will be able to see the anonymous roles added in the roles field in the /_security/_authenticate response.
* Any duplication in user roles are removed and will not show in the above authenticate response.
* In any other case, the response is unchanged.
It also introduces a behaviour change: the anonymous role resolution is now authentication node specific, previously it was authorization node specific. Details can be found at #47195 (comment)

Modified AggregatorTestCase.searchAndReduce() method so that it returns an empty aggregation result when no documents have been inserted.
Also refactored several aggregation tests so they do not re-implement method AggregatorTestCase.testCase()
Fixes#55824
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.

Implements Sum aggregation over Histogram fields by summing the value of each bucket multiplied by their count as requested in #53285
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 change adds a new setting, daily_model_snapshot_retention_after_days,
to the anomaly detection job config.
Initially this has no effect, the effect will be added in a followup PR.
This PR gets the complexities of making changes that interact with BWC
over well before feature freeze.

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`
may declare its own phases.
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.
