design: version-specific downgrade actions
Some new features, like client-specific ssl certificates, require additional
steps at downgrade, so add this to the design. Two things should be noted.
- There cannot be explicit version-specific upgrade actions; upgrades
are carried out by the old version which cannot know about new features
coming with the new version.
- Any version-specific downgrade tasks need to be carried out before switching
the binaries, so that we can resume the downgrade still using the version
knowledgeable of the new features.
