Cumulative backport of async search changes (#53635)
* Submit async search to work only with POST (#53368) Currently the submit async search API can be called using both GET and POST at REST, but given that it submits a call and creates internal state, POST should be the only allowed method. * Refine SearchProgressListener internal API (#53373) The following cumulative improvements have been made: - rename `onReduce` and `notifyReduce` to `onFinalReduce` and `notifyFinalReduce` - add unit test for `SearchShard` - on* methods in `SearchProgressListener` shouldn't need to be public as they should never be called directly, they only need to be overridden hence they can be made protected. They are actually called directly from a test which required some adapting, like making `AsyncSearchTask.Listener` class package private instead of private - Instead of overriding `getProgressListener` in `AsyncSearchTask`, as it feels weird to override a getter method, added a specific method that allows to retrieve the Listener directly without needing to cast it. Made the getter and setter for the listener final in the base class. - rename `SearchProgressListener#searchShards` methods to `buildSearchShards` and make it static given that it accesses no instance members - make `SearchShard` and `SearchShardTask` classes final * Move async search yaml tests to x-pack yaml test folder (#53537) The yaml tests for async search currently sit in its qa folder. There is no reason though for them to live in a separate folder as they don't require particular setup. This commit moves them to the main folder together with the other x-pack yaml tests so that they will be run by the client test runners too. * [DOCS] Add temporary redirect for async-search (#53454) The following API spec files contain a link to a not-yet-created async search docs page: * [async_search.delete.json][0] * [async_search.get.json][1] * [async_search.submit.json][2] The Elaticsearch-js client uses these spec files to create their docs. This created a broken link in the Elaticsearch-js docs, which has broken the docs build. This PR adds a temporary redirect for the docs page. This redirect should be removed when the actual API docs are added.
