[baremetal] cleanup: Parameterize VCP hostnames

We already define the hostnames in a central location
(openstack_init), so use the reclass params instead of hardcodes.
Also handle hardcoded hostnames in system.haproxy.proxy.listen
and system.mongodb.server.cluster.

This will also simplify later changes for novcp scenarios.
