Need to create stories to account for whatever 'day of' or 'preparing for day of' steps required to actually switch over to pre-merge testing AND the promotion to production steps (+ release notes, removing 'held back' list, etc.)

Generally, steps like:

Before Wed. Promotion:

1. code freeze
2. ‘sync-branches’
3. QE to validate master
4. Update to our promotion documentation and/or scripts?
5. Do we need a new way to generate/broadcast release notes

   [eliran] done - see OCMUI-3034

6. decommision/delete ‘Held Back’ wiki?

   [eliran] yes

On Wed. Promotion:

• If all of the above is in place, then on Wed. Promotion we can promote master/Staging ‘as is’ to stable/Production.

After Wed. Promotion:

• Would need to change in GitHub PR’s ‘# Approvers required’ from 2 to 3.
• Would need to add a checklist for QE reviewers.
• Once above is done, we can start officially requiring Pre-Merge testing before merging MRs into staging.
