From: Derrick Stolee <derrickstolee@xxxxxxxxxx>
Add the boilerplate for an "update-ref" command in the sequencer. This
connects to the current no-op do_update_ref() which will be filled in
after more connections are created.
The syntax in the todo list will be "update-ref <ref-name>" to signal
that we should store the current commit as the value for updating
<ref-name> at the end of the rebase.
