PGs are not completely drained from the OSD which is being removed using "ceph orch osd rm <osdid> --force" command.

If we are replacing a OSD then we marking the OSD out but in case of draining the OSD we are setting the crush weight to 0 but not marking the OSD as out.

    def start_draining(self) -> bool:
        if self.stopped:
            logger.debug(f"Won't start draining {self}. OSD draining is stopped.")
            return False

        else:
