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.

DIB_DISTRIBUTION_MIRROR:
   :Required: No
   :Default: None
   :Description: To use a CentOS Yum mirror, set this variable to the mirror URL
                 before running bin/disk-image-create. This URL should point to
                 the directory containing the ``5/6/7`` directories.
   :Example: ``DIB_DISTRIBUTION_MIRROR=http://amirror.com/centos``

DIB_CLOUD_IMAGES:
  :Required: No
  :Description: Set the desired URL to fetch the images from.  ppc64le:
                Currently the CentOS community is working on providing the
                ppc64le images. Until then you'll need to set this to a local
                image file.
  :Example: ``DIB_CLOUD_IMAGES=/path/to/my/centos/7/CentOS-7-x86_64-GenericCloud.qcow2.xz``
