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.
