As of elastic#53261 today `PlainListenableActionFuture` is the sole implementation of `ListenableActionFuture`, the reason for the `Plain...` prefix is now lost. It also heavily uses variable shadowing in its implementation which makes it quite hard to read, uses a mix of `volatile` fields and mutexes, and keeps hold of the deferred listeners even after completion. Finally it does not have many tests. This commit drops the unnecessary interface and renames the class to simply `ListenableActionFuture`. It reworks the implementation to avoid shadowing variables, drops the deferred listeners on completion, and moves to an entirely mutex-based implementation. Finally, it adds another test that it works as advertised.
