This commit fixes the inequality symbol used in a test assertion in
RepositoryS3SettingsTests#testInvalidChunkBufferSizeRepositorySettings. The
inequality symbol was previously backwards but fixed in commit
cad0608cdb but fixing the inequality
symbol here was missed in that commit.
Closes#18449
Currently rounding intervals obtained by nextRoundingValue() for hour, minute and
second units can include an extra hour when happening at DST transitions that add
an extra hour (eg CEST -> CET). This changes the rounding logic for time units
smaller or equal to an hour to fix this.
Closes#18326
This commit adds simple GC overhead logging. This logging captures
intervals where the JVM is spending a lot of time performing GC but it
is not necessarily the case that each GC is large. For a start, this
logging is simple and does not attempt to incorporate whether or not the
collections were efficient (that is, we are only capturing that a lot of
GC is happening, not that a lot of useless GC is happening).

We are currently only parsing the array-syntax for the rescore part
in SearchSourceBuilder ("rescore" : [ {...}, {...} ]) . We also need
to support "rescore" : {...}

- Moves recovery logic into IndexShard
- Simplifies logic to cancel peer recovery of shard where recovery source node changed
- Ensures routing entry is set on initialization of IndexShard
With this commit we clear all caches after testing the parent circuit breaker.
This is necessary as caches hold on to circuit breakers internally. Additionally,
due to usage of CircuitBreaker#addWithoutBreaking() in caches, it's even possible
to go above the limit. As a consequence, all subsequent requests fall victim to
the limit.
Hence, right after the parent circuit breaker tripped, we clear all caches to
reduce these circuit breakers to 0 again. We also exclude the clear caches
transport request from limit check in order to ensure it will succeed. As this is
typically a very small and low-volume request, it is deemed ok to exclude it.
Closes#18325
Two of the snippets in validate weren't working properly so they are
marked as skip and linked to this:

We didn't properly handle empty parameter values. We were sending
them as the literal string "null". Now we do better and send them
as the empty string.
This commit adds a variety of real disk metrics for the block devices
that back Elasticsearch data paths. A collection of statistics are read
from /proc/diskstats and are used to report the raw metrics for
operations and read/write bytes.
