Description of problem:
ceph osds restart is taking too much time and the congerge step of a minor update will most likely timeout .  In this cluster, we have 16 osds per node and 10 nodes which means 160 osds to update.

In the output below, you can see the first node took ~1 hour to restart all its osds and the second 27 minutes.
