Add support for batched upgrades to composable upgrades
Some services (e.g ceph mon) require upgrading in batches (the old upgrade architecture did the ceph mon upgrade one controller at a time). This interface enables doing the same, and over time we can probably move more services into this interface (e.g when services support rolling upgrades) to reduce downtime.
