This commit introduces a new thread pool, `system_read`, which is
intended for use by system indices for all read operations (get and
search). The `system_read` pool is a fixed thread pool with a maximum
number of threads equal to lesser of half of the available processors
or 5. Given the combination of both get and read operations in this
thread pool, the queue size has been set to 2000. The motivation for
this change is to allow system read operations to be serviced in spite
of the number of user searches.
In order to avoid a significant performance hit due to pattern matching
on all search requests, a new metadata flag is added to mark indices
as system or non-system. Previously created system indices will have
flag added to their metadata upon upgrade to a version with this
capability.
Additionally, this change also introduces a new class, `SystemIndices`,
which encapsulates logic around system indices. Currently, the class
provides a method to check if an index is a system index and a method
to find a matching index descriptor given the name of an index.

Split the autoscaling decider into a service and configuration
in order to enable having additional context information available
in the service. Added AutoscalingDeciderContext holding generic
information all deciders are expected to need. Implemented GET

There is no point in timing out a join attempt any more once a cluster
is entirely in 7.x. Timing out and retrying with the same master is
pointless, and an in-flight join attempt to one master no longer blocks
attempts to join other masters. This commit deprecates this unnecessary
setting and removes its effect from the joining process.
Relates #60873 which removes this setting in master.
This adds a force-merge step to the searchable snapshot action, enabled by default,
but parameterizable using the `force_merge-index" optional boolean.
eg.
```
PUT _ilm/policy/my_policy
{
"policy": {
"phases": {
"cold": {
"actions": {
"searchable_snapshot" : {
"snapshot_repository" : "backing_repo",
"force_merge_index": true
}
}
}
}
}
}
```

This commit makes IpFieldMapper extend ParametrizedFieldMapper. It also
updates the IpFieldMapper docs to add the ignore_malformed parameter,
which was not previously documented.
Changes:
* Moves `Retrieve selected fields` to its own page and adds a title abbreviation.
* Adds existing script and stored fields content to `Retrieve selected fields`
* Adds a xref for `Retrieve selected fields` to `Search your data`
* Adds related redirects and updates existing xrefs
Uses `my-data-stream` in place of `logs` for data stream examples.
This provides a more intuitive experience for users that copy/paste
their own values into snippets.

The current `tee` command appends a definition to
`/etc/apt/sources.list.d/elastic-{version}.list`.
This can lead to duplicate lines and significantly slow apt-get
operations.
This updates the command to overwrite rather than append.
This commit fixes the list dangling indices response.
The dangling_indices array is an array of objects
