Description

This means aggressive clients can consume unbounded mds memory.

See mon/mgr/osd throttlers for comparison:

../src/ceph_mon.cc:  msgr->set_policy_throttlers(entity_name_t::TYPE_OSD, daemon_throttler,
../src/ceph_mon.cc:  msgr->set_policy_throttlers(entity_name_t::TYPE_MDS, daemon_throttler,
../src/ceph_osd.cc:  ms_public->set_policy_throttlers(entity_name_t::TYPE_CLIENT,
../src/mgr/DaemonServer.cc:  msgr->set_policy_throttlers(entity_name_t::TYPE_CLIENT,
