Code Issues Proposed changes

Remove dict-compat from the image object

Browse Source 
This patch removes the need of having dictcompat from
the image object. Luckily we have around 5 objects in
zun that would need this changes.

DictCompat is not really needed, since that's the old
way of referencing an object field just like a dictionary
object in python.

Currently a better way needs to be implemented to avoid
conversion of the image object to a dict
back and forth. This could be achieved if we implement
the API validation blueprint.
