e2e: retry getting the Services for Ceph MON on failures

Browse Source 
In case listing the Kubernetes Services fails, the following error is
returned immediately:

    failed to create configmap with error failed to list services: etcdserver: request timed out

Wrapping the listing of the Services in a PollImmediate() routine, adds
a retry in case of common temporary issues.
