Add OCP upgrade stage for RHOSO 18

[dlaw4608]

Port upgrade functionality from openshift-ir-plugin to support sequential
OCP upgrades on OSP 18. Supports versions 4.16-4.22

Passed manually in RHOSO deployment:

TASK [shiftstack.stages.upgrade : Display upgrade completion] ******************
ok: [localhost] => {
    "msg": "Successfully upgraded cluster from 4.21 to 4.22"
}

Next step is adding a job definiton for upgrade_4.21_to_4.22_osp18.yaml in ci-framework
Then E2E validation can be ran.

But this PR needs to be merged first

Hey Daniel, the ansible-lint CI is failing with 3 violations in collection/stages/roles/upgrade/tasks/single_upgrade.yml:

1. risky-shell-pipe - line 86 (task: "Get the OCP release digest")
2. risky-shell-pipe - line 116 (task: "Wait until the upgrade starts (Progressing=True)")

Shell tasks using pipes need the pipefail option so failures in any part of the pipe are caught. Fix by prepending set -o pipefail && to the command:

- name: Get the OCP release digest
  ansible.builtin.shell:
    cmd: set -o pipefail && your_command | grep something

3. jinja[spacing] - line 161 (warning, but blocks the required production profile)

Remove the extra spaces around the outer parentheses:

- {{ ( ((finish_time | to_datetime('%Y-%m-%dT%H:%M:%S')) - (start_time | to_datetime('%Y-%m-%dT%H:%M:%S'))).total_seconds() / 60 ) | int }}
+ {{ (((finish_time | to_datetime('%Y-%m-%dT%H:%M:%S')) - (start_time | to_datetime('%Y-%m-%dT%H:%M:%S'))).total_seconds() / 60) | int }}

Once these 3 are fixed, CI should go green.
