purge-binary-logs/:host/:port/:logFileAPI endpoint, supporting?force=truepurge-binary-logswill now refuse purging, by default, if the host has replicas which have not yet applied events in the binary logs to-be-purged.This is a strict sanity check. A more relaxed one would be to check if the replicas have copied the binary logs as relay logs. This is good enough on a normal flow, but since relay logs are purged on a
change master tocommand, they can lose their ability to replicas. Soorchestratorplays safe.
