Parameters for queue.playNow.
Play the queue entry at index now, moving it to the front first when it is not already there. An empty queue fails with NOT_FOUND, an index past the end with INVALID_INDEX. When the entry has to be moved and the queue cannot be rebuilt, the call fails with OPERATION_FAILED and playback is not started.
Expected content version for optimistic concurrency control. When mismatched, mutations are aborted with STALE_TARGET (details.current carries current version). Omitted, no check is made.
