Allow logged text installs, Branched and Rawhide 

This is an attempt to add features desirable for creating
Taskotron base images. It extends the 'release' handling for
virt-install images in several ways to allow requesting of
'branched' and 'rawhide' image creation. It also adds an arg
to request virt-install image creation run in text mode, not
graphical mode. Graphical mode is what we always want for
openQA (so the installed OS doesn't have kernel params intended
for serial console interaction), but for Taskotron purposes,
we want the install run in text mode.
