Composable Neutron Core Compute Plugin

Create a new resource registry entry for a Neutron "compute plugin".

For ML2 this may be the same os the NeutronComputePlugin but patches
for other vendors will follow that require extra bits on nodes
where VMs will be created.

This patch removes the ML2 code from the compute role and instead
uses the existing composable services.

NOTE: we are able to remove the puppet resource chain to force OVS to
get restarted due to puppet-neutron commit:
Idb1332dd498bb3065720f2ccaf68e6b0e9fa80c3 which should resolve that
issue.
