Andrew Audibert 8e421f5cc6 [tf.data service] Add client/server version mismatch error.
We raise an error instead of logging a warning because client/server mismatch is likely to cause hangs or other failures that will be easier to debug if the user gets a direct error message instead of needing to discover the warning in their logs.
