The patchset is a next step on the way of fixing the buckets being deleted on master while still having RO refs on replicas.
It makes the master talk to replicas about which buckets they allow to GC, i.e. which of them have no RO refs anymore. The consulting is done in batches, in background, and doesn't affect incoming user requests.
The next part will be about introducing stricter _bucket changes validation via on_replace triggers.
