Often PRs require one-time manual intervention, which cannot or should not be encapsulated into a Salt state. Currently, these are recorded in an ad-hoc fashion and can be easily forgotten, especially with a remote team. I'd like to make this better in a few parts with more consistent communciation:

• Any commit requiring a migration task should use a 'saltfs-migration: ' tag in the commit message, e.g. 520adf2
• Automation (homu? A saltfs-specific bot? Something existing?) will check for these tags in the commit messages on a PR; if any are found, then after merging add a comment to the PR containing a todo list with each tag as an item. It should also add a new S-needs-migration tag
• Whoever runs the Salt highstate with those changes should check off the migration items when they are done, and then remove the tag (manually? via bot?).
