James Rodewig a63f60b776 [DOCS] Remove heading offsets for REST APIs (#44568)
Several files in the REST APIs nav section are included using
:leveloffset: tags. This increments headings (h2 -> h3, h3 -> h4, etc.)
in those files and removes the :leveloffset: tags.

Other supporting changes:
* Alphabetizes top-level REST API nav items.
* Change 'indices APIs' heading to 'index APIs.'
* Changes 'Snapshot lifecycle management' heading to sentence case.

Jason Tedor 0045111ce2 Deprecate the suggest metrics (#29627)
The suggest stats were folded into the search stats as part of the
indices stats API in 5.0.0. However, the suggest metric remained as a
synonym for the search metric for BWC reasons. This commit deprecates
usage of the suggest metric on the indices stats API.

Similarly, due to the changes to fold the suggest stats into the search
stats, requesting the suggest index metric on the indices metric on the
nodes stats API has produced an empty object as the response since
5.0.0. This commit deprecates this index metric on the indices metric on
the nodes stats API.

Enable selecting adaptive selection stats
The node stats API enables filtlering the top-level stats for only
desired top-level stats. Yet, this was never enabled for adaptive
replica selection stats. This commit enables this. We also add setting
these stats on the request builder, and fix an inconsistent name in a
setter.

David Roberts a292740b9e Add cgroup memory usage/limit to OS stats on Linux (#26166)
This change adds cgroup memory usage/limit to the OS stats section of
the node stats on Linux.  This information is useful because in Docker
containers the standard node stats report the host memory limit, not
taking account of extra restrictions that may have been applied to the
container.

The original idea was to store these values as Long, truncating any values
outside the range of long.  However, this meant that in the relatively common
case of no limit being applied, users would not see the same value in the OS
stats as they see by querying Linux directly.  So instead the values are stored
as String.  This change places a burden on consumers of the strings to
convert the strings to numbers and decide what to do about extremely large
values, but there will be very few consumers and they would need to have a
policy for dealing with "no limit" in any case.

Jason Tedor 41ffb008ad Fix doc bug for cgroup cpuacct usage metric
This commit fixes a silly doc bug where the field that represents the
total CPU time consumed by all tasks in the same cgroup was mistakenly
reported as "usage" instead of "usage_nanos".

Today when parsing a stats request, Elasticsearch silently ignores

Jason Tedor 900ee0536e Strengthen handling of unavailable cgroup stats
On some systems, cgroups will be available but not configured. And in
some cases, cgroups will be configured, but not for the subsystems that
we are expecting (e.g., cpu and cpuacct). This commit strengthens the
handling of cgroup stats on such systems.

This commit adds a variety of real disk metrics for the block devices

operations and read/write bytes.

Martijn van Groningen 2fa33d5c47 Added ingest statistics to node stats API
The ingest stats include the following statistics:
* `ingest.total.count`- The total number of document ingested during the lifetime of this node
* `ingest.total.time_in_millis` - The total time spent on ingest preprocessing documents during the lifetime of this node
* `ingest.total.current` - The total number of documents currently being ingested.
* `ingest.total.failed` - The total number ingest preprocessing operations failed during the lifetime of this node

Also these stats are returned on a per pipeline basis.

Jason Tedor df598e8129 Modify load average formats
This commit modifies the load_average in the node stats API response
to be an object containing the one-minute, five-minute and
fifteen-minute load averages as fields (if those values are
available). Additionally, this commit modifies the cat nodes API
response to format the one-minute, five-minute and fifteen-minute load
averages as null if any of the respective values are not available.

Alexander Reelsen bb275166f1 Simplify nodes stats API
First, this breaks backwards compatibility!

* Removed /_cluster/nodes/stats endpoint
* Excpect the stats types not as parameters, but as part of the URL
* Returning all indices stats by default, returning all nodes stats by default
* Supporting groups & types in nodes stats now as well
* Updated documentation & tests accordingly
* Allow level parameter for "shards" and "indices" (cluster does not make sense here)

Lee Hinman a754224751 Add field data memory circuit breaker.
This adds the field data circuit breaker, which is used to estimate
the amount of memory required to load field data before loading it. It
then raises a CircuitBreakingException if the limit is exceeded.

It is configured with two parameters:

`indices.fielddata.cache.breaker.limit` - the maximum number of bytes
of field data to be loaded before circuit breaking. Defaults to
`indices.fielddata.cache.size` if set, unbounded otherwise.

`indices.fielddata.cache.breaker.overhead` - a contast for all field
data estimations to be multiplied with before aggregation. Defaults to
1.03.

Both settings can be configured dynamically using the cluster update
settings API.
