Description

reported here: https://marc.info/?l=ceph-users&m=159091210202115&w=2

for every operation we need to check if notifications are configured for the bucket, this is done via a call to: "rgw_get_system_obj()"
however, on large scale, this is overloading a one OSD.

note that when OSD replies with ENOENT (when no topics are configured for that user), this reply is not cached, so, OSD is being queries for every op
