Separate tuned daemon setup into a role.
Currently, profiles for the tuned daemon are set only for
OpenShift node(s). This excludes the OpenShift loadbalancer.
As a result, ARP cache limits on loadbalancers are not raised.
This causes problems with HA setups where loadbalancers serve
1k+ OpenShift nodes.
This commit ensures the openshift-control-plane role is applied
to loadbalancers, masters and OpenShift infra nodes. Regular
OpenShift worker nodes get the openshift-node profile.
