It would be useful to have a way to test a agent config image in dev-scripts. An example workflow of the test would be:

• build an unconfigured installer iso (https://issues.redhat.com/browse/AGENT-574)
• run this as a live iso by mounting it as a CD and booting,similar to what we do with the agent iso (note that in a factory install this image will be written to disk but I'm not not sure we need to exercise that step
• build a configuration image (https://issues.redhat.com/browse/AGENT-559)
• mount this as a separate disk after the unconfigured iso has booted
• verify that the configuration is read and all files are updated
• verify that the installation process continues
