[atomic-devel] show what deployment is hotfixed

[Dusty Mabe <dusty dustymabe com>]

If I `ostree admin unlock --hotfix` a clean clone is created for me to rollback to. That 
is pretty awesome. The only thing I don't like is that it's not too clear from a call to 
`rpm-ostree status` that the deployment I'm on is "dirty". Would it be reasonable to open
an issue to request some marker (can be a single character) added to the output to know 
if a deployment has been hotfixed? See example output below:


-bash-4.3# ostree admin unlock --hotfix

Hotfix mode enabled.  A writable overlayfs is now mounted on /usr
for this booted deployment.  A non-hotfixed clone has been created
as the non-default rollback target.
