Adds opengl/mesa to cais-compute ansible role

[andriy-safe-ai]

Ran ansible-playbook cais_* to install packages.

Ran the following ansible playbook to make sure that packages are present on all compute nodes:

---

- name: Check if package is installed
  hosts: compute
  become: true
  tasks:
    - name: Gather the package facts
      ansible.builtin.package_facts:
        manager: auto
#    - name: Print the package facts
#      ansible.builtin.debug:
#        var: ansible_facts.packages
    - name: Check whether the package mesa-libOSMesa  is installed
      ansible.builtin.debug:
        msg: "{{ ansible_facts.packages['mesa-libOSMesa'] | length }} versions of mesa-libOSMesa are installed!"
      when: "'mesa-libOSMesa' in ansible_facts.packages"
    - name: Check whether the package mesa-libOSMesa-devel is installed
      ansible.builtin.debug:
        msg: "{{ ansible_facts.packages['mesa-libOSMesa-devel'] | length }} versions of mesa-libOSMesa-devel are installed!"
      when: "'mesa-libOSMesa-devel' in ansible_facts.packages"
    - name: Check whether the package glfw is installed
      ansible.builtin.debug:
        msg: "{{ ansible_facts.packages['glfw'] | length }} versions of glfw are installed!"
      when: "'glfw' in ansible_facts.packages"
    - name: Check whether the package glfw-devel is installed
      ansible.builtin.debug:
        msg: "{{ ansible_facts.packages['glfw-devel'] | length }} versions of glfw-devel are installed!"
      when: "'glfw-devel' in ansible_facts.packages"
    - name: Check whether the package mesa-libGL is installed
      ansible.builtin.debug:
        msg: "{{ ansible_facts.packages['mesa-libGL'] | length }} versions of mesa-libGL are installed!"
      when: "'mesa-libGL' in ansible_facts.packages"
    - name: Check whether the package mesa-libGL-devel is installed
      ansible.builtin.debug:
        msg: "{{ ansible_facts.packages['mesa-libGL-devel'] | length }} versions of mesa-libGL-devel are installed!"
      when: "'mesa-libGL-devel' in ansible_facts.packages"

Results("ok" means that the packages are present):

Fix the commit message to make it declarative then it looks good to me. I changed the title as such if you wanted to see the example.

Why Declarative? What's wrong with imperative?

Even official Git documentation recommends imperative: https://stackoverflow.com/questions/3580013/should-i-use-past-or-present-tense-in-git-commit-messages

[steven-safeai]

It's the style "I grew up with" at Google. Meant to be read as "this commit adds blah."

[andriy-safe-ai]

Updated commit message.
