Since [1] we can't use osd pool without replicas (size: 1) by default.
We now need to set the mon_allow_pool_size_one flag to true in the ceph
configuration and add the --yes-i-really-mean-it flag to the osd pool
set size cli.

The current ceph cluster health is in warning state:
health: HEALTH_WARN
13 pool(s) have no replicas configured
2 pool(s) have non-power-of-two pg_num
Because we're using only 1 replica then we need to disable the redundancy
check.
The pool pg num should be a power of two number (like 16).

Add a new functional test that deploys a Ceph cluster with three nodes
for MON, OSD and MDS and then runs shrink-mds.yml to test it.
