Starting code for removing item data snapshots,
backups, and backup details that have been
orphaned. Data can become orphaned through either
incomplete backup delete operations (older
corso versions) or because backups didn't
complete successfully
This code doesn't cover all cases (see TODOs in
PR) but gets a lot of the boiler-plate that will
be required. Future PRs will build on what's in
here to close the gaps
This code is not wired into any corso operations
so it cannot be run outside of unit tests
