Use index UUID to lookup indices on IndicesService
Today we use the index name to lookup index instances on the IndicesService
which applied to search requests but also to index deletion etc. This commit
moves the interface to expect an Index instance which is a tuple
and looks up the index by uuid rather than by name. This prevents accidental modification
of the wrong index if and index is recreated or searching from the wrong index in such a case.
Accessing an index that has the same name but different UUID will now result in an IndexNotFoundException.

Occasionally the .geohash suffix in Geo{Distance|DistanceRange}Query would conflict with a mapping that defines a sub-field by the same name. This occurs often with nested and multi-fields a mapping defines a geo_point sub-field using the field name "geohash". Since the QueryParser already handles parsing geohash encoded geopoints without requiring the ".geohash" suffix, the suffix parsing can be removed altogether.
This commit removes the .geohash suffix parsing, adds explicit test coverage for the nested query use-case, and adds random distance queries to the nested query test suite.
In particular, this test ensures we don't restart the master node until
we know the index deletion has taken effect on master and the master
eligible nodes.

This change makes ScoreSortBuilder implement NamedWriteable, adds
equals() and hashCode() and also implements parsing ScoreSortBuilder
back from xContent. This is needed for the ongoing Search refactoring.
This was lost in refactoring even on the 2.x branch. The slow-log
is not per index not per shard anymore such that we don't add the
shard ID as the logger prefix. This commit adds back the index
name as part of the logging message not as a prefix on the logger
for better testabilitly.
Closes#17025
_wait_for_completion defaults to false. If set to true then the API will
wait for all the tasks that it finds to stop running before returning. You
can use the timeout parameter to prevent it from waiting forever. If you
don't set a timeout parameter it'll default to 30 seconds.
Also adds a log message to rest tests if any tasks overrun the test. This
is just a log (instead of failing the test) because lots of tasks are run
by the cluster on its own and they shouldn't cause the test to fail. Things
like fetching disk usage from the other nodes, for example.
Switches the request to getter/setter style methods as we're going that
way in the Elasticsearch code base. Reindex is all getter/setter style.
Closes#16906
Currently the message stays in the `UnassignedInfo` for the shard,
however, it would be very useful to know the exact point (time-wise)
that the cancellation happened when diagnosing an issue.

Apparently lucene6 is way more picky with respect to corrupting files
that are not fsynced that's why this test sometimes failed after the lucene6
upgrade.
This commit reduces the maximum number of threads required in the
bootstrap check. This limit can be reduced since the generic thread pool
is no longer unbounded.
Relates #17003
The generic thread pool was previously configured to be able to create
an unlimited number of threads. The thinking is that tasks that are
submitted to its work queue must execute and should not block waiting
for a worker. However, in cases of heavy load, this can lead to an
explosion in the number of threads; this can even lead to a feedback
loop that exacerbates the problem. What is more, this can even bump into
OS limits on the number of threads that can be created.
This commit limits the number of threads in the generic thread pool to
four times the bounded number of processors.

This merge commit merges #16682 which adds the ability to define a index-global
default similarity but at the same time prevents overriding built-in similarities
for new indices. Old indices where able to do this int the past which should not
be punished even though this is not possible anymore.
Closes#16594Closes#16682
This removes the need for accessing the SearchContext when parsing Sort elements
to queries. After applying the patch only a QueryShardContext is needed.
