Vlad Lazar 8fe3f17c47 storcon: improve drain and fill shard placement (#8119) ...

## Problem
While adapting the storage controller scale test to do graceful rolling
restarts via
drain and fill, I noticed that secondaries are also being rescheduled,
which, in turn,
caused the storage controller to optimise attachments.

## Summary of changes
* Introduce a transactional looking rescheduling primitive (i.e. "try to
schedule to this
secondary, but leave everything as is if you can't")
* Use it for the drain and fill stages to avoid calling into
`Scheduler::schedule` and having
secondaries move around.
