purge-cluster: do not set group name vars at playbook level

This has the behavior of overriding custom values set in group_vars.
I've added defaults to the rest of the group names so that if they are
not overridden in group_vars then defaults will be used.

See: https://bugzilla.redhat.com/show_bug.cgi?id=1354700
