Description of problem:

Attempt deployment of two CNS clusters associated with a single OCP cluster managed by a single heketi instance/pod -- based on the description of parameter glusterfs_cluster this should be supported:  "...a single heketi service is expected to manage multiple distinct clusters. NOTE: For natively-hosted clusters, all pods will be in the same OpenShift namespace " [1] Official docs [2] also indicate management of multiple clusters is supported: "Heketi allows administrators to add and remove storage capacity by managing either a single or multiple Red Hat Gluster Storage clusters." The limitation with openshift-ansible deployment is that both clusters will reside in the same namespace/project, which is acceptable.

Deployment of CNS is succcessful, but only a single cluster is configured, despite hostvars configured to deploy multiple CNS clusters out of box.

How reproducible:
Always

Steps to Reproduce:
1. Configure inventory with 2 sets of 3 gluster nodes, with each set containing hostvars for a unique glusterfs_cluster ID (e.g. glusterfs_cluster=1, glusterfs_cluster=2) 
2. Execute openshift-ansible config.yml

Actual results:
No errors but all glusterfs nodes are associated with a single cluster -- observed via 'heketi-cli cluster list'

Expected results:

'heketi-cli cluster list' shows two unique clusters provisioned.
