History
Ian Wienand 9f688f53da centos7; use numeric DIB_RELEASE 
With the introduction of centos 8 we have constructs like

 if [[ $DISTRO =~ (centos|fedora) && $DIB_RELEASE -ge 8 ]]

This is intended to match the "centos7" element (from the =~) but it
was missed that this is setting the DIB_RELEASE to "GenericCloud".

I think it makes more sense for this to be a numeric release, and
makes constructs like above work.  There really isn't any other type
of image to choose here; thus we move it into a new, centos7
specific variable.

Note that when the centos 8 images are available, we want to move to a
generic "centos" element that will handle both 7 and 8 together (same
as rhel) based on DIB_RELEASE and deprecate centos7; this works with
that environment too.
