Tolerate unready ceph-mon endpoints

Browse Source 
This allows ceph to form a reliable quorum under Kubernetes
1.6.  There appears to be a minor timing difference in 1.6
compared to previous versions requiring us to annotate the
ceph-mon service with this toleration.

# In kubernetes 1.6 and beyond, it seems there was a change in behavior
# requiring us to tolerate unready endpoints to form a quorum. I can only
# guess at some small timing change causing statefulset+2 to not see the
# now ready statefulset+1, and because we do not tolerate unready endpoints
# a newly provisioned ceph-mon will most certainly never see itself in the
# peer list. This change allows us to form a quorum reliably everytime
