Title: Coordinator drop/remove related stuff.

- DruidCoordinatorCleanup should wait for availableSegments to populate
before dropping any segments.
- Clarify that millisToWaitBeforeDeleting applies to "removing" rather than
"dropping" segments.
- LoadRule shouldn't need to wait for the deletionWaitTime before dropping
excess replicas.
