obsolete: add operation metadata to rebase/amend/histedit obsmarkers
By recording what operation created the obsmarker, we can show very intuitive
messages to the user in various UIs. For instance, log output could have
messages like "Amended as XXX" to show why a commit is old and has an 'x' on it.
