The NUMA technology would be handled by the resource agent, if it was
told by Pacemaker which utilization zone to use on its host.  I just
need the policy engine to do more granular resource placement and
communicate the selected zone to the resource agents on the hosts.

I'm pretty sure there's no direct support for this, but there might be
different approaches I missed.  Thus I'm looking for ideas here.
