Rewrite Rename backend in a more atomic fashion
Move the core of renaming logic into the DB. This guarantees a
lot more atomicity than we have right now (our current solution,
removing the container from the DB and re-creating it, is *VERY*
not atomic and prone to leaving a corrupted state behind if
things go wrong. Moving things into the DB allows us to remove
most, but not all, of this - there's still a potential scenario
where the c/storage rename fails but the Podman rename succeeds,
and we end up with a mismatched state.
