`Fog::Connection` is a wrapper around XML parsing behaviour which is no
longer in `fog-core` but will be moved to `fog-xml`
So should be using `Fog::Core::Connection` for the simpler behaviour.
Seeing a lot of churn in lib/fog/brightbox/compute.rb because of adding
new requests or models as well as any implementation changes.
This moves the common behaviour between Compute's Real and Mock
classes into their own file to cut down on the noise when refactoring or
merging.
Brightbox is now moving to using the default Ubuntu Cloud Images
(http://cloud-images.ubuntu.com/) where we are also using the naming
convention used there.
So the image selector has been updated to select the latest version of
Ubuntu (i386, official Brightbox) image if no image is specified with
the new format.
