Fix lookup support in adjacency matrix (backport of #59099) (#59108)
This request:
```
POST /_search
{
  "aggs": {
    "a": {
      "adjacency_matrix": {
        "filters": {
          "1": {
            "terms": { "t": { "index": "lookup", "id": "1", "path": "t" } }
          }
        }
      }
    }
  }
}
```

Would fail with a 500 error and a message like:
```
{
  "error": {
    "root_cause": [
      {
        "type": "illegal_state_exception",
        "reason":"async actions are left after rewrite"
      }
    ]
  }
}
```

This fixes that by moving the query rewrite phase from a synchronous
call on the data nodes into the standard aggregation rewrite phase which
can properly handle the asynchronous actions.

Add data stream timestamp validation via metadata field mapper (#59002)
Backport of #58582 to 7.x branch.

This commit adds a new metadata field mapper that validates,
that a document has exactly a single timestamp value in the data stream timestamp field and
that the timestamp field mapping only has `type`, `meta` or `format` attributes configured.
Other attributes can affect the guarantee that an index with this meta field mapper has a
useable timestamp field.

The MetadataCreateIndexService inserts a data stream timestamp field mapper whenever
a new backing index of a data stream is created.

David Turner 2fdd8f3a2c Restores do not cause red health (#59015)
Since 2.0.0 (56a264cf6d) we have documented that restoring a snapshot
typically results in `red` cluster health. However since 5.0.0 (#19516)
this hasn't been true, we report `yellow` health for unassigned
primaries that will be recovered from a snapshot in the future. This
commit adjusts these docs to match today's behaviour.

[7.x] SQL: fix handling of escaped chars in JDBC connection string (#58429) (#58977)
SQL: fix handling of escaped chars in JDBC connection string (#58429)

This commit fixes an issue emerging when the connection string URI
contains escaped characters.

The original URI is pre-parsed in order to re-assemble a new URI having
the optional elements filled in with defaults. The new URI has been
using however the unescaped query and fragment parts. So if these
contained any escaped `&` or `=` (such as in the password option value),
the unescaping would reveal them and make them later interfere with the
options parsing.

The commit changes that, so that the new URI be built from the unescaped
"raw" parts of the original URI.

(cherry picked from commit 94eb5a05e79c6e203de548d05b13e00295bd4489)

Account for recovery throttling when restoring snapshot (#58658) (#58811)
Restoring from a snapshot (which is a particular form of recovery) does not currently take recovery throttling into account
(i.e. the `indices.recovery.max_bytes_per_sec` setting). While restores are subject to their own throttling (repository
setting `max_restore_bytes_per_sec`), this repository setting does not allow for values to be configured differently on a
per-node basis. As restores are very similar in nature to peer recoveries (streaming bytes to the node), it makes sense to
configure throttling in a single place.

The `max_restore_bytes_per_sec` setting is also changed to default to unlimited now, whereas previously it was set to
`40mb`, which is the current default of `indices.recovery.max_bytes_per_sec`). This means that no behavioral change
will be observed by clusters where the recovery and restore settings were not adapted.

Account for remaining recovery in disk allocator (#58800)
Today the disk-based shard allocator accounts for incoming shards by
subtracting the estimated size of the incoming shard from the free space on the
node. This is an overly conservative estimate if the incoming shard has almost
finished its recovery since in that case it is already consuming most of the
disk space it needs.

This change adds to the shard stats a measure of how much larger each store is
expected to grow, computed from the ongoing recovery, and uses this to account
for the disk usage of incoming shards more accurately.

Add index block api (#58716)
Adds an API for putting an index block in place, which also ensures for write blocks that, once successfully returning to
the user, all shards of the index are properly accounting for the block, for example that all in-flight writes to an index have
been completed after adding the write block.

This API allows coordinating more complex workflows, where it is crucial that an index is no longer receiving writes after
the API completes, useful for example when marking an index as read-only during an upgrade in order to reindex its
documents.

[7.x][ML] Add status and increased estimate to memory usage (#58588) (#58606)
Adds parsing of `status` and `memory_reestimate_bytes`
to data frame analytics `memory_usage`. When the training surpasses
the model memory limit, the status will be set to `hard_limit` and
`memory_reestimate_bytes` can be used to update the job's
limit in order to restart the job.

Backport of #58588

Introduce node.roles setting (#58512)
Today we have individual settings for configuring node roles such as
node.data and node.master. Additionally, roles are pluggable and we have
used this to introduce roles such as node.ml and node.voting_only. As
the number of roles is growing, managing these becomes harder for the
user. For example, to create a master-only node, today a user has to
configure:
 - node.data: false
 - node.ingest: false
 - node.remote_cluster_client: false
 - node.ml: false

at a minimum if they are relying on defaults, but also add:
 - node.master: true
 - node.transform: false
 - node.voting_only: false

If they want to be explicit. This is also challenging in cases where a
user wants to have configure a coordinating-only node which requires
disabling all roles, a list which we are adding to, requiring the user
to keep checking whether a node has acquired any of these roles.

This commit addresses this by adding a list setting node.roles for which
a user has explicit control over the list of roles that a node has. If
the setting is configured, the node has exactly the roles in the list,
and not any additional roles. This means to configure a master-only
node, the setting is merely 'node.roles: [master]', and to configure a
coordinating-only node, the setting is merely: 'node.roles: []'.

With this change we deprecate the existing 'node.*' settings such as
'node.data'.

Add Variable Width Histogram Aggregation (backport of #42035) (#58440)
Implements a new histogram aggregation called `variable_width_histogram` which
dynamically determines bucket intervals based on document groupings. These
groups are determined by running a one-pass clustering algorithm on each shard
and then reducing each shard's clusters using an agglomerative
clustering algorithm.

This PR addresses #9572.

The shard-level clustering is done in one pass to minimize memory overhead. The
algorithm was lightly inspired by
[this paper](https://ieeexplore.ieee.org/abstract/document/1198387). It fetches
a small number of documents to sample the data and determine initial clusters.
Subsequent documents are then placed into one of these clusters, or a new one
if they are an outlier. This algorithm is described in more details in the
aggregation's docs.

At reduce time, a
[hierarchical agglomerative clustering](https://en.wikipedia.org/wiki/Hierarchical_clustering)
algorithm inspired by [this paper](https://arxiv.org/abs/1802.00304)
continually merges the closest buckets from all shards (based on their
centroids) until the target number of buckets is reached.

The final values produced by this aggregation are approximate. Each bucket's
min value is used as its key in the histogram. Furthermore, buckets are merged
based on their centroids and not their bounds. So it is possible that adjacent
buckets will overlap after reduction. Because each bucket's key is its min,
this overlap is not shown in the final histogram. However, when such overlap
occurs, we set the key of the bucket with the larger centroid to the midpoint
between its minimum and the smaller bucket’s maximum:
`min[large] = (min[large] + max[small]) / 2`. This heuristic is expected to
increases the accuracy of the clustering.

Nodes are unable to share centroids during the shard-level clustering phase. In
the future, resolving https://github.com/elastic/elasticsearch/issues/50863
would let us solve this issue.

It doesn’t make sense for this aggregation to support the `min_doc_count`
parameter, since clusters are determined dynamically. The `order` parameter is
not supported here to keep this large PR from becoming too complex.

[DOCS] Note that DS timestamp field mapping changes require reindex (#58444) (#58517)
With #58096, data streams now track the timestamp field mapping outside
of the template associated with the stream. This means you can no longer
update the timestamp field mapping using template changes.

This updates the associated data stream docs.

[7.x] [ML] calculate cache misses for inference and return in stats (#58252) (#58363)
When a local model is constructed, the cache hit miss count is incremented.

When a user calls _stats, we will include the sum cache hit miss count across ALL nodes. This statistic is important to in comparing against the inference_count. If the cache hit miss count is near the inference_count it indicates that the cache is overburdened, or inappropriately configured.
