Checking for clean PGs is a recurring event when reconciling nodes
for upgrades and fencing. No need to log every request.

When a cluster is updated with a different image version, this triggers
a serialized restart of all the pods. Prior to this commit, no safety
check were performed and rook was hoping for the best outcome.
Now before doing restarting a daemon we check it can be restarted. Once
it's restarted we also check we can pursue with the rest of the
platform. For instance, with monitors we check that they are in quorum,
for OSD we check that PGs are clean and for MDS we make sure they are
all active.

this adds a structure to hold various settings related to executing ceph
cli commands, and introduces a common interface for configuring and
running such commands.

The CephCluster resource will now expose the health of the ceph cluster
so admins can query the status with k8s api or kubectl instead of
needing to run the rook toolbox. The operator will query the
ceph status periodically and update the status in the custom resource.
