Clearing the collection filtering metadata is not a safe operation and must only be done by coordinator-like entities and must only happen under a critical section. This ticket has two purposes:

1. Log the reason for clearing of the filtering metadata so we have better traceability in the logs
2. Add invariants/tasserts that the clearing only happens under the critical section. If any violations of this exist, document them and see if there is a better programming pattern to achieve them.
