Execute the given action and subsequent callback immediately if the current thread is the herder's tick thread,
or use them to create and store a {@link DistributedHerderRequest} on the request queue and return the resulting request
if not.
@param action the action that should be run on the herder's tick thread
@param callback the callback that should be invoked once the action is complete
@return a new {@link DistributedHerderRequest} if one has been created and added to the request queue, and {@code null} otherwise
