I've been playing these and wondering what these really do.  I know engine-iso-uploader and engine-image-uploader really work since I've used them but the others don't do anything useful or give me wrong information.  I'm running these on the Engine VM in a hosted-engine deployment with version 3.64.

engine-config list outputs nothing at all.  I won't try the others yet.

engine-manage-domains edit --domain=Adomain simply tells me the the domain adomain does not exist and it's converted it all to lowercas
