Description of problem:
The results of an upgrade with MDS services running on the controller nodes is that the Ceph Ansible, due to its limitations, is setting all of the MDS services as active, instead of 1 active and 2 passive.
After the upgrade the Ceph cluster status is:
$ sudo ceph -s
cluster:
id: c18db176-6a52-11e8-818d-525400af03d6
health: HEALTH_WARN
insufficient standby MDS daemons available
clock skew detected on mon.controller-0
services:
mon: 3 daemons, quorum controller-1,controller-2,controller-0
mgr: controller-2(active), standbys: controller-0, controller-1
mds: cephfs-3/3/3 up {0=controller-0=up:active,1=controller-2=up:active,2=controller-1=up:active}

Version-Release number of selected component (if applicable):
ceph-ansible-3.1.0-0.1.rc3.el7cp.noarch
puppet-tripleo-8.3.2-6.el7ost.noarch
openstack-tripleo-puppet-elements-8.0.0-2.el7ost.noarch
openstack-tripleo-common-8.6.1-19.el7ost.noarch
How reproducible:
100%
Steps to Reproduce:
1. Deploy OSP 12 overcloud with MDS services
2. Upgrade to OSP 13 and Ceph 3.x
3. Validate the status of the Ceph cluster
Actual results:
As showed in the description, the Ceph cluster status is on Warning with 3 active MDS services
Expected results:
The default overcloud status for MDS services, with 1 active and 2 standby

The validation from TripleO side is blocked by https://bugzilla.redhat.com/show_bug.cgi?id=1757570.
The Ceph QE can validate this bug by upgrading Ceph 2.5 -> Ceph 3.1 with MDS running.
