Make a version-less RHEL element to handle both '7' and '8' DIB_RELEASE.
The element usage should align with other elements which operate in the
same way such as the Fedora element.
Additionally, this patch adds support for RHEL8 that operates with
Python 3.
As of now, users of diskimage-builder will still be able to use the
'rhel7' element, or migrate to 'rhel' and specify their respective
DIB_RELEASE value.
* mount the xfs file-system for extraction as read-only. vaguely
based on explaination in [1] and the fact we only read the image
data into a tar, so can ignore this.
XFS (dm-1): Superblock has unknown read-only compatible features (0x4) enabled.
* Use the redhat system python as the dib-python version. dib was
ahead of it's time making an abstracted python interpreter for
system work ;) the system python should work for running the various
dib element scripts.

redhat-common
Image installation steps common to RHEL, CentOS, and Fedora.
Requirements:
If used to build an image form a cloud image compress with xz (the default in centos), this element uses "unxz" to decompress the image. Depending on your distro you may need to install either the xz or xz-utils package.
Environment Variables
- DIB_LOCAL_IMAGE
-
- Required
-
No
- Default
-
None
- Description
-
Use the local path of a qcow2 cloud image. This is useful in that you can use a customized or previously built cloud image from diskimage-builder as input. The cloud image does not have to have been built by diskimage-builder. It should be a full disk image, not just a filesystem image.
- Example
-
DIB_LOCAL_IMAGE=rhel-guest-image-7.1-20150224.0.x86_64.qcow2
- DIB_DISABLE_KERNEL_CLEANUP
-
- Required
-
No
- Default
-
0
- Description
-
Specify if kernel needs to be cleaned up or not. When set to true, the bits that cleanup old kernels will not be executed.
- Example
-
DIB_DISABLE_KERNEL_CLEANUP=1
