Align node_ips hiera keys with the service name.
To enable composable generation of this switch the key names
to align with the service_name of each service.
Note that this should depend on I423b544df174254ac511b906b0c570e701678022
and previously passed CI with that defined, but because we now run
gate validation jobs on puppet-tripleo it's impossible to land, so
this now contains both old and new hiera keys temporarily, which will
be removed when the puppet-tripleo patch lands.
