The _upgrade API has been superseded by the _reindex API and was deprecated in 7.11.0. This commit removes it completely for the 8.0.0 release.

Resolves #21337

indices upgrade api (/_upgrade or /{index}/_upgrade) was removed and _reindex is suggested to be used instead.
There is no easy way to translate _upgrade request to _reindex requests. The dummy Upgrade action will return an exception to a user with a message indicating that _reindex should be used.
