Prohibit the usage of create index api in namespaces managed by data stream templates (#62574)
Backport of #62527 to 7.x branch.

This commit adds validation that prohibits the creation of regular indices
in the namespace of templates with data streams enabled.

It shouldn't be possible to create ordinary indices when the name of the index
matches with a composable index template that enables data streams. Auto creation
has logic that creates data streams instead of regular indices. However validation
logic for the create index api was missing.

Faster sequential access for stored fields (#62509) (#62573)
Faster sequential access for stored fields

Spinoff of #61806
Today retrieving stored fields at search time is optimized for random access.
So we make no effort to keep state in order to not decompress the same data
multiple times because two documents might be in the same compressed block.
This strategy is acceptable when retrieving a top N sorted by score since
there is no guarantee that documents will be on the same block.
However, we have some use cases where the document to retrieve might be
completely sequential:

Scrolls or normal search sorted by document id.
Queries on Runtime fields that extract from _source.
This commit exposes a sequential stored fields reader in the
custom leaf reader that we use at search time.
That allows to leverage the merge instances of stored fields readers that
are optimized for sequential access.
This change focuses on the fetch phase for now and leverages the merge instances
for stored fields only if all documents to retrieve are adjacent.
Applying the same logic in the source lookup of runtime fields should
be trivial but will be done in a follow up.

The speedup on queries sorted by doc id is significant.
I played with the scroll task of the http_logs rally track
on my laptop and had the following result:

Alan Woodward 5421a743a7 Move SearchLookup into FetchContext (#62549)
FetchSubPhase#getProcessor currently takes a SearchLookup parameter. This
however is only needed by a couple of subphases, and will almost certainly change in
future as we want to simplify how fetch phases retrieve values for individual hits.

To future-proof against further signature changes, this commit moves the SearchLookup
reference into FetchContext instead.

The data frame structure in c++ has a limit on 2^32 documents. This commit

This adds ILM support for automatically migrating the managed

This proposal makes use of a MigrateAction that is injected
(similar to how the Unfollow action is injected) in phases that
don't define index allocation rules using the AllocateAction or
don't explicitly define the MigrateAction itself (regardless if it's
enabled or disabled).

Fix RestrictedTrustManagerTests on Zulu8 (#62436)
Since #61857 we test using BCJSSE (Bouncy Castle SSL) when running on
Zulu8 because Azul have backported SSL changes from Java11 into their
Java8 JRE which prevents us from using Sun JSSE in FIPS mode.

BCJSSE uses different exception messages than Sun JSSE, so we needed
to update
RestrictedTrustManagerTests.testThatDelegateTrustManagerIsRespected
to reflect the fact that sometimes we might be receive BCJSSE error
messages on a Java8 JVM

[ML] fixes testWatchdog test verifying matcher is interrupted on timeout (#62391) (#62447)
Constructing the timout checker FIRST and THEN registering the watcher allows the test to have a race condition.

The timeout value could be reached BEFORE the matcher is added. To prevent the matcher never being interrupted, a new timedOut value is added to the watcher thread entry. Then when a new matcher is registered, if the thread was previously timedout, we interrupt the matcher immediately.

Oidc additional client auth types (#58708) (#62289)
The OpenID Connect specification defines a number of ways for a
client (RP) to authenticate itself to the OP when accessing the
Token Endpoint. We currently only support `client_secret_basic`.

This change introduces support for 2 additional authentication
methods, namely `client_secret_post` (where the client credentials
are passed in the body of the POST request to the OP) and
`client_secret_jwt` where the client constructs a JWT and signs
it using the the client secret as a key.

Support for the above, and especially `client_secret_jwt` in our
integration tests meant that the OP we use ( Connect2id server )
should be able to validate the JWT that we send it from the RP.
Since we run the OP in docker and it listens on an ephemeral port
we would have no way of knowing the port so that we can configure
the ES running via the testcluster to know the "correct" Token
Endpoint, and even if we did, this would not be the Token Endpoint
URL that the OP would think it listens on. To alleviate this, we
run an ES single node cluster in docker, alongside the OP so that
we can configured it with the correct hostname and port within
the docker network.

Implement fields fetch for runtime fields (backport of #61995) (#62416)
This implements the `fields` API in `_search` for runtime fields using
doc values. Most of that implementation is stolen from the
`docvalue_fields` fetch sub-phase, just moved into the same API that the
`fields` API uses. At this point the `docvalue_fields` fetch phase looks
like a special case of the `fields` API.

While I was at it I moved the "which doc values sub-implementation
should I use for fetching?" question from a bunch of `instanceof`s to a
method on `LeafFieldData` so we can be much more flexible with what is
returned and we're not forced to extend certain classes just to make the
fetch phase happy.

I also caught a few bugs with query generation caused by missing
`@Override` annotations and fixed a few of them. There is a bug with
`regexp` queries with match options that I'm not fixing in this PR but
will get to later.

We want Logstash indices to be system indices, but the logstash
service will still need to be able to manage its indices. This PR
adds special system index APIs to the logstash plugin so that
logstash can manage its pipelines without direct access to the
underlying indices.

* Add logstash module with dedicated logstash APIs
* merge with x-pack plugin
* add system index access allowance
* Break out serialization tests into distinct classes
* Log failures for partial multiget failure
* Move LogstashSystemIndexIT to javaRestTest task

[7.x] Add "synthetics-*-*" templates for synthetics fleet data (#62193) (#62346)
* Add "synthetics-*-*" templates for synthetics fleet data

For the Elastic Agent we currently have `logs` and `metrics`, however, synthetic data doesn't belong
with those and thus we should have a place for it to live. This would be data reported from
heartbeat and under the 'monitoring' category.

This commit adds a composable index template for `synthetics-*-*` indices similar to the work in
 #56709 and #57629.

David Roberts e4275f3749 [ML] Use utility thread pool for memory estimation (#62314)
The job comms thread pool is intended for the long-running job
processes that do anomaly detection or data frame analytics and
count towards job count and memory limits.

This commit moves the short-lived memory estimation processes
to the ML utility thread pool.

Although this doesn't matter in most cases, at the limits of
scale it could mean that memory estimations would get in the way
of starting jobs, or would queue up for an excessive period of
time while waiting for jobs to finish.

Nhat Nguyen 3d69b5c41e Introduce point in time APIs in x-pack basic (#61062)
This commit introduces a new API that manages point-in-times in x-pack
basic. Elasticsearch pit (point in time) is a lightweight view into the
state of the data as it existed when initiated. A search request by
default executes against the most recent point in time. In some cases,
it is preferred to perform multiple search requests using the same point
in time. For example, if refreshes happen between search_after requests,
then the results of those requests might not be consistent as changes
happening between searches are only visible to the more recent point in
time.

A point in time must be opened before being used in search requests. The
`keep_alive` parameter tells Elasticsearch how long it should keep a
point in time around.

```
POST /my_index/_pit?keep_alive=1m
```

The response from the above request includes a `id`, which should be
passed to the `id` of the `pit` parameter of search requests.

```
POST /_search
{
    "query": {
        "match" : {
            "title" : "elasticsearch"
        }
    },
    "pit": {
            "id":  "46ToAwMDaWR4BXV1aWQxAgZub2RlXzEAAAAAAAAAAAEBYQNpZHkFdXVpZDIrBm5vZGVfMwAAAAAAAAAAKgFjA2lkeQV1dWlkMioGbm9kZV8yAAAAAAAAAAAMAWICBXV1aWQyAAAFdXVpZDEAAQltYXRjaF9hbGw_gAAAAA==",
            "keep_alive": "1m"
    }
}
```

Point-in-times are automatically closed when the `keep_alive` is
elapsed. However, keeping point-in-times has a cost; hence,
point-in-times should be closed as soon as they are no longer used in
search requests.

```
DELETE /_pit
{
    "id" : "46ToAwMDaWR4BXV1aWQxAgZub2RlXzEAAAAAAAAAAAEBYQNpZHkFdXVpZDIrBm5vZGVfMwAAAAAAAAAAKgFjA2lkeQV1dWlkMioGbm9kZV8yAAAAAAAAAAAMAWIBBXV1aWQyAAA="
}
```

#### Notable works in this change:

- Move the search state to the coordinating node: #52741
- Allow searches with a specific reader context: #53989
- Add the ability to acquire readers in IndexShard: #54966

The all (but one) share the same main logic: use a two phase iterator, iterate over all documents, and decide whether the current doc matches or not based on what the script returns. I went ahead and shared this bit of code in the base class for all queries on top of runtime fields.

David Roberts 969a1c558b [ML] Include the "properties" layer in find_file_structure mappings (#62158)
Previously the "mappings" field of the response from the
find_file_structure endpoint was not a drop-in for the
mappings format of the create index endpoint - the
"properties" layer was missing.  The reason for omitting
it initially was that the assumption was that the
find_file_structure endpoint would only ever return very
simple mappings without any nested objects.  However,
this will not be true in the future, as we will improve
mappings detection for complex JSON objects.  As a first
step it makes sense to move the returned mappings closer
to the standard format.

This is a small building block towards fixing #55616

Luca Cavanna b680d3fb29 Async search: don't track fetch failures (#62111)
Fetch failures are currently tracked byy AsyncSearchTask like ordinary shard failures. Though they should be treated differently or they end up causing weird scenarios like total=num_shards and successful=num_shards as the query phase ran fine yet the failed count would reflect the number of shards where fetch failed.

Given that partial results only include aggs for now and are complete even if fetch fails, we can ignore fetch failures in async search, as they will be anyways included in the response. They are in fact either received as a failure when all shards fail during fetch, or as part of the final response when only some shards fail during fetch.

Rename runtime_script field type to runtime (#62034)
We've had some discussions around the user experience when using runtime fields. Although we do plan on having multiple runtime fields implementation (e.g. grok, lookup etc.) which could be exposed as different field types, we decided to expose all runtime fields under the same `runtime` type. At the moment, the only implementation will be through scripts, hence a `script` must be specified. In the future, there will be other ways to generate values for runtime fields besides scripts.

This translates also to renaming the RuntimeScriptFieldMapper class to RuntimeFieldMapper .

Improve reduction of terms aggregations (#61779) (#62028)
Today, the terms aggregation reduces multiple aggregations at once using a map

to lookup every bucket in a global map with no particular order.
This commit changes how term buckets are sorted by shards and partial reduces in
order to be able to reduce results using a merge-sort strategy.
For bwc, results are merged with the legacy code if any of the aggregations use
a different sort (if it was returned by a node in prior versions).

The changes included in this commit that were made outside of the x-pack/plugin/runtime-fields directory are minimal and revolve around 1) making the ScriptService available while parsing index mappings so that the scripts associated to runtime fields can be compiled 2) sharing code to manipulate ranges etc. as it can be reused in runtime fields.
