Build RL8+OFED image in CI (#427)

* Check major version for RL8 package installs

* Gather facts on ofed role

* Support kernel checks with mismatching version length

4.18.0-553.16.1.el8_9.x86_64
4.18.0-553.el8_9.x86_64
These would fail with the error:

'<' not supported between instances of 'str' and 'int'.

as the community.general.version_sort was trying to compare the `el8_9` of the latter with the `16` of the former.

Strip the last two chunks so we just compare numbers.

* Move to LTS version now RL9.4 is supported

* Fail when any inventory source cannot be parsed

* Always reboot after selinux and package updates

* Cleat facts before OFED so install will match newest kernel

* Clear facts after reboot so OFED install will match newest kernel

* fail caas and stackhpc if any inventory can't be read

* make reboot conditional on package or SELinux changes again

* include OFED in both RL8 and RL9 builds

* always run CI tests on RL8 and RL9

* allow concurrent RL8/RL9 CI tests

* mark pending reboot check as not a change

* fix workflow matrix definitions

* bump CI images - now both OFED

* use reboot hint for checking reboot required
