debugbackupbundle: introduce command to interact with strip backups

This vendors backups extension from hg-experimental.

Listing backups and having some utility to apply them is nice. I know we have
obsmarkers now, but this will help a lot of end users who still uses strip until
we get evolve out of experimental.
