[6.13.z] Add support for overriding jira issues to comment on.

[Satellite-QE]

Cherrypick of PR: #15427

Problem Statement

• We have a --jira-comments pytest option that we use to add comments to Jira issues for tests marked with Verifies or BlockedBy doc fields. Atm, this can't be overridden, and one has to mark each test with these fields.
• The JPL team has requested this enhancement so that we can use it in standalone PRT runs.

Solution

• Update logic for --jira-comments to override issues to comment test results on.

Usage

• pytest tests/foreman/api/test_ping.py --jira-comments Comment test results on issues mentioned in Verifies and BlockedBy doc fields(No change, this is primary use case).
• pytest tests/foreman/api/test_ping.py --jira-comments 'SAT-24796,SAT-25230' Comment test results on SAT-24796 and SAT-25230.

Related Issues

• SAT-25884
• Add support for reporting/commenting test results to the Jira issue #15104
