Also removed custom code that was required in the REST tests due to this.

Add transport.publish_port setting

Add transport.publish_port setting to allow users to specify the port
other cluster members should use when connecting to an instance. This
is needed for systems such as OpenShift, where cluster communication
needs to use a publicly accessibly proxy port, because the normal port
(9300) is bound to a private loopback IP address.
Add documentation for transport.publish_port
Fix HistogramAggregationSearchBenchmark.
[SPEC] path without {index} is not allowed for indices.open api
[SPEC] Removed empty paths from close and delete index apis

Although the empty paths are still registered in the java RestActions, that is only to return a meaningful error in case the index is not provided.
Index/indices are now mandatory.
Remove unnecessary optimize call that destabelizes test
[DOCS] Fixed file:/// URL for installing plugins
[DOCS] Added documentation for CAT Aliases API

Added asciidoc. Added new lines in java class.
Added no-cache infrastucture the the filter cache.

During query parsing if a filter is encountered that extends from NoCacheFilter then the filter will not be given to the filter cache (also not wrapped in FilterCacheFilterWrapper).
Also if a filter directly or indirectly wraps a NoCacheFilter then that filter will also not be cached.

Relates to #4757
Made sure that any filter that wraps a p/c filter (has_child & has_parent) either directly or indirectly will never be cached by making CustomQueryWrappingFilter extend from NoCacheFilter.

Closes #4757
Consume the entire weight and pre compute the DocIdSets for all segments instead of keeping the weight around and build a DocIdSet when a segment is being processed. This fixes issues where the has_child / has_parent filter produce no results or errors on subsequent scan requests.

Also made CustomQueryWrappingFilter implement Releasable in order to cleanup the pre-computed DocIdSets.

Closes #4703
[SPEC] Removed create.json
Create is a special API that is most simply and safely
implemented by calling the index() api with op_type
set to true.
[SPEC] Various API fixes
Including:
* change some string params to list
* make some params or bodies required
* removed incorrect URLs
* removed incorrect params
* Fixed name of pending_tasks
fix IndexOutOfBoundsException on _all field without tokens and keyword analyzer

fix AllEntries to only compute boost when there are actually some Entries available for the _all field

Closes #4771
[TESTS] Mapping update might get applied before the first document is indexed on replica, so it is better not to check if the new field isn't available before re-indexing first document.
Documentation typo.
