[openstack-dev] [tripleo] [ironic] Where to keep discover images

I'm wondering.... Rather than have a static config, could the
DiscoverdInspect interface handle setting up the TFTP config, pulling
those images from Glance, etc, when a node is moved into the "inspect"
state (assuming such integration was desired by the cloud operator)?
