[baremetal] Retire mas01 NAT

Isolate networks by retiring NAT on mas01; also cutting direct
internet access from cluster nodes that are not facing the public
network (prx, cmp).

NOTE: Since we are removing mas01 NAT, VCP VMs (except prx which have
public IPs) and kvm nodes (cmp also have public IPs) will no longer
have direct internet connectivity.
Cluster deployment and operations will work without it, but if it is
required for different reasons, the MaaS proxy could be enabled by
uncommenting the /etc/enviroment section in:
- cluster.baremetal-mcp-pike-common-ha.include.proxy.yml
