What is it good for?

Troubleshooting resource allocation problems
Understanding the big picture of placement resource view
Verify test cases: there are code to integrate with nova functional and

placement gabbi tests

Most probably `$ openstack resource provider tree list ` run against a big

deployment will blow the client but you can still use `$ openstack resource provider tree show <rp_uuid> `
