StatsD support works, working on dashboards
As documented here http://docs.openstack.org/developer/ironic/deploy/metrics.html
Ironic allows performance metrics to be dumped via StatsD, this installs StatsD
on the undercloud via epel, sets up a service for it, enables it, and updates
Ironic to use it.
