ceph nodes cannot be safely updated in 5.1 release

we need to write down to release notes that user, if he wants should update ceph manually

for nodes containing monitors he should install new packages and restart monitors

once all the monitors are restarted, he should update code on the OSD nodes one by one waiting for OSD nodes to rebuild cleanly after OSD restart. for this to happen, user should check `ceph pg dump` command output for absence of non-'active+clean' states.

Also, user should reconsider ceph update if there are already unclean pgs in ceph pg dump output.
