This commit removes the method Strings#splitStringToArray and replaces
the call sites with invocations to String#split. There are only two
explanations for the existence of this method. The first is that
String#split is slightly tricky in that it accepts a regular expression
rather than a character to split on. This means that if s is a string,
s.split(".") does not split on the character '.', but rather splits on
the regular expression '.' which splits on every character (of course,
this is easily fixed by invoking s.split("\\.") instead). The second
possible explanation is that (again) String#split accepts a regular
expression. This means that there could be a performance concern
compared to just splitting on a single character. However, it turns out
that String#split has a fast path for the case of splitting on a single
character and microbenchmarks show that String#split has 1.5x--2x the
throughput of Strings#splitStringToArray. There is a slight behavior
difference between Strings#splitStringToArray and String#split: namely,
the former would return an empty array in cases when the input string
was null or empty but String#split will just NPE at the call site on
null and return a one-element array containing the empty string when the
input string is empty. There was only one place relying on this behavior
and the call site has been modified accordingly.
Folds the helper class for random object generation into the
abstract sort test class. Removes a few references to ESTestCase
that were not needed due to inheriting from it along the way.
The query shard reset() method resets some internal state in the
query shard context, like clearing query names, the filter flag
or named queries. The problem with this method being public is
that it currently (miss?) used for modifying an existing context
for recursive invocatiob, but the contexts that have been reseted
that way cannot be properly set back to their previous state.
This PR is a step towards removing reset() entirely by first making
it only be used internally in QueryShardContext. In places where
reset() was used we can either create new QueryShardContexts or
modify the existing context because it is discarded afterwards anyway.
Today, the constructor for IngestDocument#FieldPath does a string
concatentation and two object allocation on every field path. This
commit removes these unnecessary operations.

With this commit we compress HTTP responses provided the client
supports it (as indicated by the HTTP header 'Accept-Encoding').
We're also able to process compressed HTTP requests if needed.
The default compression level is lowered from 6 to 3 as benchmarks
have indicated that this reduces query latency with a negligible
increase in network traffic.

This commit removes an unnecessary if statement in Bootstrap#check. The
removed if statement was duplicating the conditionals in the nested if
statements and was merely an artifact of an earlier refactoring.
Today when running in production mode the bootstrap checks are
completely unforgiving. But there are cases where an end-user might not
have the ability to modify some of the system-level settings that cause
the bootstrap checks to trip (e.g., guest settings that are inherited
from a host and can not be modified). This commit adds a setting that
allows system-level bootstrap checks to be ignored for these
end-users. We classify certain bootstrap checks into system-level checks
and only those bootstrap checks will be ignored if this flag is
enabled. All other bootstrap checks are still subject to being enforced
if the user is in production mode. We will still log warnings for these
bootstrap checks because the end-user does still need to be made aware
that they are running in a configuration that is less-than-ideal from a
resiliency perspective.

This commit removes a racy but unnecessary assertion in scaling thread
pool idle test. Namely, the main test thread can reach the removed
assertion before the last few threads in the thread pool have completed
their tasks and caused the completed tasks count on the underlying
executor to be updated. But this assertion is unnecessary. The main test
thread already waits on a latch that is only decremented immediately
before a task completes. This ensures that it was in fact the case that
every submitted task was executed.

When the termslookup (mocked in this case) doesn't return any terms, the
query used to rewrite to an empty boolean query. Now it rewrites to a
MatchNoDocsQuery. This changes the test expectation accordingly.
Closes#18071
This commit modifes the EsThreadPoolTestCase#info helper method to
return null when info for the thread pool can not be found. This really
should only happen for the "same" thread pool, and so we also assert
that we only get to a place where there is no info if the thread pool
that info was requested for is in fact the "same" thread pool. Not
returning null here and instead throwing an exception would fail tests
that tried to lookup info on the "same" thread pool.
