This commit forbids the changing of thread pool types for any thread
pool. The motivation here is that these are expert settings with
little practical advantage.

Removes the mapping transform feature which when used made debugging very
difficult. Users should transform their documents on the way into
Elasticsearch rather than having Elasticsearch do it.
Closes#12674
The only way to refer to the plain highlighter is now `plain`, the only way to refer to the fast vector highlighter is `fvh` and the only way to refer to the postings highlighter is `postings`. The name variants like `highlighter`, `postings-highlighter` and `fast-vector-highlighter` have been removed.
We have two types of parse methods for queries: one for the inner query, to be used once the parser is positioned within the query element, and one for the whole query source, including the query element that wraps the actual query.
With the search refactoring we ended up using the former in count, cat count and delete by query, whereas we should have used the former. It ends up working properly given that we have a registered (deprecated) query called "query", which used to allow to wrap a filter into a query, but this has the following downsides:
1) prevents us from removing the deprecated "query" query
2) we end up supporting a top level query that is not wrapped within a query element (pre 1.0 syntax iirc that shouldn't be supported anymore)
This commit finally removes the "query" query and fixes the related parsing bugs. We also had some tests that were providing queries in the wrong format, those have been fixed too.

Closes#13954
The NotQueryBuilder has been deprecated on the 2.x branches
and can be removed with the next major version. It can be
replaced by boolean query with added mustNot() clause.
Closes#13761
This adds an API for force merging lucene segments. The `/_optimize` API is now
deprecated and replaced by the `/_forcemerge` API, which has all the same flags
and action, just a different name.
This commit removes some cache concurrency level settings that were
applicable when the cache was backed by the Guava cache implementation,
but no longer apply with the cache implementation completed in #13717.
