…7582) Today when following a new leader index, we fetch the remote cluster state, check the remote cluster license, check the user privileges, retrieve the index shard stats before initiating a CCR restore session. But if the leader index to follow is closed, we're executing a bunch of operations that would inevitability fail at some point (on retrieving the index shard stats, because this type of request forbid closed indices when resolving indices). We could fail a Put Follow request at the first step by checking the leader index state directly from the remote cluster state. This also helps the Resume Follow API to fail a bit earlier.
