Description of problem:
When upgrade to v3.9 using playbooks, it failed to apply PersistentVolumeClaim.

Version-Release number of selected component (if applicable):
ose-ansible: v3.9.0-0.35.0.0

How reproducible:
always

Steps to Reproduce:
1. deploy metrics v3.7 

openshift_metrics_cassandra_pvc_size=10Gi
openshift_metrics_cassandra_storage_type=dynamic
openshift_metrics_image_version=v3.7
openshift_metrics_image_prefix=registry.example.com/openshift3/
openshift_metrics_install_metrics=true


2. redeploy metrics v3.9
openshift_metrics_cassandra_pvc_size=10Gi
openshift_metrics_cassandra_storage_type=dynamic
openshift_metrics_image_version=v3.7
openshift_metrics_image_prefix=registry.example.com/openshift3/
openshift_metrics_install_metrics=true
