Create composable mapping between enabled services and role ips

Create composable mapping between enabled services and role ips

Currently we have a hard-coded list of ips for various services that
run on the controller, instead we can dynamically generate that list
of per-service ips, initially only for the controller but this approach
can be extended so it works for any role.
