Remote-executor threads should not block to acquire locks

    Description

      Currently, enabling the queue on the remote-executor thread pool can cause deadlocks, because a CommitCommand/1PCPrepareCommand could end up in the queue while a remote-executor thread is busy waiting to acquire the same lock that this commit would release.

      If trying to acquire a lock would free the thread until the key has been acquired, we could enable the queue on the remote-executor/OOB thread pools, and we would need a lot less threads for the same load.
