Motivations:
* Shorten the code some more
* Use ActionListener#wrap to get easy to reason about behavior in failure scenarios
* Remove duplication in the logic of handling snapshot completion listeners (listeners removing themselves and comparing snapshots to their targets)
* Also here, move all listener handling into `SnapshotsService` and remove custom listener class by putting listeners in a map
