bifrost: Use the pre-built XCI OS images instead of dib

We already have images for all 3 distros which we could simply re-use
for all the XCI VM deployments instead of building new ones everytime
with DIB. The images will be copied to the new VM from the cache
directory if they are available otherwise we will simply download them
during the XCI execution phase.
