Add a `_freeze` / `_unfreeze` API (#35592)

This commit adds a rest endpoint for freezing and unfreezing an index.
Among other cleanups mainly fixing an issue accessing package private APIs
from a plugin that got caught by integration tests this change also adds
documentation for frozen indices.
Note: frozen indices are marked as `beta` and available as a basic feature.

Relates to #34352

= Frozen Indices
[partintro]
--
Elasticsearch indices can require a significant amount of memory available in order to be open and searchable. Yet, not all indices need
to be writable at the same time and have different access patterns over time. For example, indices in the time series or logging use cases
are unlikely to be queried once they age out but still need to be kept around for retention policy purposes.
In order to keep indices available and queryable for a longer period but at the same time reduce their hardware requirements they can be transitioned
into a frozen state. Once an index is frozen, all of its transient shard memory (aside from mappings and analyzers)
is moved to persistent storage. This allows for a much higher disk to heap storage ratio on individual nodes. Once an index is
frozen, it is made read-only and drops its transient data structures from memory. These data structures will need to be reloaded on demand (and subsequently dropped) for each search request that targets the frozen index. A search request that hits
one or more frozen shards will be executed on a throttled threadpool that ensures that we never search more than
`N` (`1` by default) searches concurrently (see <<search-throttled>>). This protects nodes from exceeding the available memory due to incoming search requests.
In contrast to ordinary open indices, frozen indices are expected to execute slowly and are not designed for high query load. Parallelism is
gained only on a per-node level and loading data-structures on demand is expected to be one or more orders of a magnitude slower than query
execution on a per shard level. Depending on the data in an index, a frozen index may execute searches in the seconds to minutes range, when the same index in an unfrozen state may execute the same search request in milliseconds.
--
== Best Practices
Since frozen indices provide a much higher disk to heap ratio at the expense of search latency, it is advisable to allocate frozen indices to
dedicated nodes to prevent searches on frozen indices influencing traffic on low latency nodes. There is significant overhead in loading
data structures on demand which can cause page faults and garbage collections, which further slow down query execution.
Since indices that are eligible for freezing are unlikely to change in the future, disk space can be optimized as described in <<tune-for-disk-usage>>.
== Searching a frozen index
Frozen indices are throttled in order to limit memory consumptions per node. The number of concurrently loaded frozen indices per node is
limited by the number of threads in the <<search-throttled>> threadpool, which is `1` by default.
Search requests will not be executed against frozen indices by default, even if a frozen index is named explicitly. This is
to prevent accidental slowdowns by targeting a frozen index by mistake. To include frozen indices a search request must be executed with
the query parameter `ignore_throttled=false`.
[source,js]
--------------------------------------------------
GET /twitter/_search?q=user:kimchy&ignore_throttled=false
--------------------------------------------------
// CONSOLE
// TEST[setup:twitter]
[IMPORTANT]
================================
While frozen indices are slow to search, they can be pre-filtered efficiently. The request parameter `pre_filter_shard_size` specifies
a threshold that, when exceeded, will enforce a round-trip to pre-filter search shards that cannot possibly match.
This filter phase can limit the number of shards significantly. For instance, if a date range filter is applied, then all indices (frozen or unfrozen) that do not contain documents within the date range can be skipped efficiently.
The default value for `pre_filter_shard_size` is `128` but it's recommended to set it to `1` when searching frozen indices. There is no
significant overhead associated with this pre-filter phase.

[[freeze-index-api]]
== Freeze Index API
++++
<titleabbrev>Freeze Index</titleabbrev>
++++
Freezes an index.
[float]
=== Request
`POST /<index>/_freeze`
[float]
=== Description
A frozen index has almost no overhead on the cluster (except
for maintaining its metadata in memory), and is blocked for write operations.
See <<frozen-indices>> and <<unfreeze-index-api>>.
[float]
=== Path Parameters
`index` (required)::
(string) Identifier for the index
//=== Query Parameters
//=== Authorization
[float]
=== Examples
The following example freezes and unfreezes an index:
[source,js]
--------------------------------------------------
POST /my_index/_freeze
POST /my_index/_unfreeze
--------------------------------------------------
// CONSOLE
// TEST[s/^/PUT my_index\n/]
[IMPORTANT]
================================
Freezing an index will close the index and reopen it within the same API call. This causes primaries to not be allocated for a short
amount of time and causes the cluster to go red until the primaries are allocated again. This limitation might be removed in the future.

<titleabbrev>Unfreeze Index</titleabbrev>

Unfreezes an index.
[float]

`POST /<index>/_unfreeze`

=== Description
When a frozen index is unfrozen, the index goes through the normal recovery
process and becomes writeable again. See <<frozen-indices>> and <<freeze-index-api>>.
[float]
=== Path Parameters
`index` (required)::
(string) Identifier for the index
//=== Query Parameters
//=== Authorization
[float]
=== Examples
