Returns {@link CompletableFuture} which will complete only after publishing of the given {@code remoteLogMetadata} into
the remote log metadata topic and the internal consumer is caught up until the produced record's offset.

@param topicIdPartition partition of the given remoteLogMetadata.
@param remoteLogMetadata RemoteLogMetadata to be stored.
@return a future with acknowledge and potentially waiting also for consumer to catch up.
This ensures cache is synchronized with backing topic.
@throws RemoteStorageException if there are any storage errors occur.
