This is an amalgamation of:

* Cory Hinshaw: Initial implementation !5552
* Rémy Coutable: Updates !9350
* Nick Thomas: Resolve conflicts and add ED25519 support !13712

Instead of running the sync 10 times, just run it twice and see if the
worker attempts other projects than it did in the first run.

If some projects fail to sync, Geo::RepositySyncWorker should not take
the same set of projects over and over again. But try to sync all of
them.
