RedHat 9 and Import Scheme Changes

Zach Graber requested to merge zeg-rhel-9 into main

There a quite a few changes included with this MR, but here is my best attempt at a high-level summary:

Major Changes (at a High-Level View)

  • Added support for RockyLinux 9 and AlmaLinux 9 in the GitLab CI pipeline
    • Created new task files for RedHat 9 support
    • Preemptively set software store to exist at /software/r9/...
  • Changed scheme for importing tasks from static, hard-coded imports to dynamic include_tasks
    • Renamed lots of individual, OS/distro-specific task files to the {{ ansible_os_family }}-{{ ansible_distribution_major_version }}.yml format to match variables.
    • Explicitly specified vars/<file> or tasks/<file> to avoid collision
    • Implements changes discussed in issue #26 (closed) ; fixes #26 (closed)
  • Switched RedHat 8 and 9 back to ML kernel
  • Extracted GPU/GRID driver rpm/deb filename into variables, along with the client config token. This should make it easier to update, should driver versions or our file structure on the runner change.
  • Separated packages role's task files for RedHat into individual files
  • Disabled aliases for ls --color=auto
  • Added a check before creating the software share directory
    • If /software already exists, the task will be skipped
    • This avoids failure on repeat runs of instance_setup

Next Steps

  • Build/publish software for RedHat 9
  • Retire CentOS 7?
  • Update Exosphere UI to advertise Rocky/Alma 9 on "Create Instance" page?

Hopefully the diffs speak for themselves. If there are any questions, I'm happy to clarify.
