Description of problem:

Issue with https://access.redhat.com/documentation/en-us/openshift_container_platform/3.9/html/installation_and_configuration/install-config-cluster-metrics#openshift-prometheus-undeploy


Rerunning this uninstallation playbook goes past this issue and it uninstalls the Prometheus. It happens repeatedly.
