Pool repositories are persisted in the database, and when the DB is
restored, the data need to be restored on disk. This is done by
resetting the state machine and rescheduling the object pool creation.

This is not an exact replica of the state like at the time of the
creation of the backup. However, the data is consistent again.

Dumping isn't required as internally GitLab uses git bundles which
bundle all refs and include all objects in the bundle that they require,
reduplicating as more repositories get backed up. This does require more
data to be stored.

This avoids Sidekiq versioning pitfalls where the deploy host schedules
a new migration, and the older Sidekiq hosts don't know about this
migration.

The automatic merging code used `--strategy=ours`, which turned out to
be incorrect; instead we wanted `--strategy=recursive
--strategy-option=ours`. This small difference results in merging
throwing away _all_ EE changes in favour of CE changes, instead of only
doing this for conflicts.

This commit ensures that EE has all the appropriate changes. The diff
was generated by cherry picking all merge commits made since two days
ago, picking them with `--strategy=recursive --strategy-option=ours`.
