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.
Similarly to what we did with the search api, we can now also move query parsing on the coordinating node for the explain api. Given that the explain api is a single shard operation (compared to search which is instead a broadcast operation), this doesn't change a lot in how the api works internally. The main benefit is that we can simplify the java api by requiring a structured query object to be provided rather than a bytes array that will get parsed on the data node. Previously if you specified a QueryBuilder it would be serialized in json format and would get reparsed on the data node, while now it doesn't go through parsing anymore (as expected), given that after the query-refactoring we are able to properly stream queries natively.

Some jenkins servers have this, but our codebase normalization doesn't
follow symlinks. Add this so that its correct.
Only really impacts tests, i suppose it helps if someone has a symlinked plugins/
but that is not recommended :)
* plugin authors can use full policy syntax, including codebase substitution
properties like core syntax.
* simplify test logic.
* move out test-framework permissions to separate file.
Closes#14311
This method needs special permission and can cause all kinds of other problems
if we are creating lots of theads. Also the reason why we added this are fixed
long ago, no need to maintain this code.
This commit fixes a regression introduced with #12058. This causes failures with the delete index api when providing the same index name multiple times in the request, or aliases/wildcard expressions that end up pointing to the same concrete index. The bug was revealed after merging #11258 as we delete indices in batch rather than one by one. The master node will expect too many acknowledgements based on the number of indices that it's trying to delete, hence the request will never be acknowledged by all nodes.
Closes#14316
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#13326Closes#14304
This commit makes QueryCache and SearcherWrappoer registration public
otherwise plugins can't access those extension points due to security restrictions.
This commit brings all the registration etc. from IndexCacheModule into
IndexModule. As a side-effect to remove a circular dependency between
IndicesService and IndicesWarmer this commit also cleans up IndicesWarmer and
separates the Engine from the warmer.
