Implement changes for IL5 ci vars

Background

After reevaluating ci var usage in #768 (closed), we should capture all of the top level dsop group ci vars as code and update how these are managed by doing the following

• We need to review #768 (closed), get signoff, and implement changes
• Create config map for each env with all needed CI vars
• Create secret with a credential to read and create ci vars at the dsop group

We should also dedupe any CI vars that we've documented as a part of the discussion in #768 (closed)

Acceptance Criteria

• Suggested changes from #768 (closed) completed
• Config map and secret created
• Configuration for prod, staging, and Il5

Definition of Done

• Write or update any unit or integration tests
• Project pipeline runs successfully
• Add any applicable checkboxes for testing e.g. Ran pipeline in staging env or pipeline-test-project pipeline run
• Solution is captured as code and/or documentation and merge requests have been submitted
• Code review completed and merge request approved/merged
• All Acceptance Criteria have been completed
