Looks like ansible's module "pacemaker_resource" is missing on undercloud.


Version-Release number of selected component (if applicable):
-------------------------------------------------------------
openstack-tripleo-heat-templates-7.0.0-0.20170805163048.el7ost.noarch
ansible-2.3.1.0-3.el7.noarch

Steps to Reproduce:
-------------------
1. Update uc
2. Setup repos on oc
3. Apply patches on uc
4. Restart heat/mistral on uc
5. Get latest images on uc
6. Re-run initial deploy command with update_noop.yaml
7. Generate list of hosts with tripleo-ansible-inventory
8. Generate updates' playbook:
    openstack overcloud config download --config-dir tmpconfig-latest
9. Run minor update against controller nodes
ansible-playbook -b -i tmp-hosts tmpconfig-latest/tripleo-VM7Mr1-config  /update_steps_playbook.yaml --limit controller

Actual results:
---------------
Attempt to run minor update fails

Expected results:
-----------------
Minor update of oc controllers succeeds
