utilization attributes of primitives can't be managed

[bitglue]

Pacemaker allows resources to be associated with some utilization of arbitrary resources. Nodes can then be said to have so much of those resources, and pacemaker will take care place resources only where there are enough resources. For example, one can declare that a resource representing a VM requires 512 MB of RAM, and that some VM host has 16 GB of RAM. See the relevant Pacemaker documentation for more.

I've started working on a branch to add the capability of managing these attributes.
