Optimize remote state stale file deletion

[shiv0408]

Description

Created an async task AsyncStaleFileDeletion which is initialized on only master eligible nodes. Once the task in initialized in RemoteClusterStateService start(), it schedules a clean up after specified interval which is added as a dynamic setting cluster.remote_store.state.cleanup_interval with 5 min default.
Clean up is also proceeded with if we have more than 10 successful states updates since last clean up. After trying clean up once, we schedule the task again after the set interval.
