sequencer: add advice for revert

In the case of merge conflicts, while performing a revert, we are
currently advised to use `git cherry-pick --<sequencer-options>`.
Introduce a separate advice message for `git revert`. Also change
the signature of `create_seq_dir` to handle which advice to display
selectively.
