OpenCloudOS is a centos-like Linux distribution.
I test kpatch in OpenCloudOS V8 and V9.
It works well in V9. But v8 itself has two problems:
1. no available epol repo, so kpatch can't install ccache.
2. executing 'uname -r' can't get an accurate kernel version.
Both problems have been notified to the OpenCloudOS community.
After they fix these problems, kpatch will work well in all versions.

VMware's Photon OS uses kpatch to build kernel livepatches, starting with 3.0.
Add some changes to support Photon OS in kpatch, so we can use kpatch-build
in Photon like:
kpatch-build <name>.patch.
This commit integrates Photon OS support into existing kpatch-build support code
for various distros.
The yum-builddep utility doesn't always install all the kernel build
dependencies. Using the --skip-unavailable flag (rhel8+) lets us skip
over packages that it can't find, but continue to install the ones it
can. (Unavailable packages are usually platform-specific or not strictly
necessary for kpatch-build's kernel build invocation.)

As I noticed, commit eaaced191 has added
partial support for openEuler.
This patch enables usage in openEuler like:
kpatch-build xxxx.patch
I test it in openEuler 21.09, for people who
want to use kpatch in openEuler, two more steps
are needed.
1) add repo source
source rpm package of openEuler kernel are put in
two places. One is
https://repo.openeuler.org/openEuler-21.09/source/
Another one is
https://repo.openeuler.org/openEuler-21.09/update/source/
The latter one is not inclued in rpm repo lists by default.
2) compile kernel with CONFIG_LIVEPATCH_PER_TASK_CONSISTENCY enabled
openEuler has its own strategy when trying to apply patches.
We can use the klp_enable_patch function only when
CONFIG_LIVEPATCH_PER_TASK_CONSISTENCY is enabled.

Shellcheck complains with the following warning:
SC2230: which is non-standard.
It is probably fair to assume that which is available for now, so just
ignore the warning.

On RHEL-8, version agnostic python-devel package does not exist.
On previous RHEL releases, python-devel is for python2.
On RHEL-8, the platform-python (which provides the needed utilities)
is python3.
Assuming this will be the same for future RHEL releases, specify the
python major as part of the kpatch dependencies.

using a direct link install epel repo and install ccache without
specifying the version.

Standard centos7 repos don't contain ccache so we have to install it
from epel just like we do on rhel7.

Use a kpatch-specific snapshot of centos7 image since we are still
running into problems we saw on fedora/ubuntu.

Add functions to prepare a separate partition/disk for cache use
(.ccache and .kpatch dirs). This is useful for vagrant images that are
generally not big enough for kpatch build.

Add test/integration/lib.sh for use in other kpatch related scripts
and or directly by end-users. Initial version contains per-distro
dependency functions, so it can be quickly installed as follows:
