Xinliang Liu a6ee4d0c21 Introduce openEuler distro
Add openeuler-minimal element and add CI functional tests for both
x86_64 and arm64.

OpenEuler is an open source community driven YUM/DNF distro like
Fedora. It references Fedora and CentOS a lot for the rpm packages
building. So somewhat it can be treated as a redhat family distro
and reuse the YUM/DNF related elements to help build openEuler images.

For more info about openEuler, see: https://openeuler.org/en

=============
redhat-common
=============
Image installation steps common to RHEL, CentOS, Fedora and openEuler.
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
