PR Merge Process

1. All PRs should be raised for stage branch first.
2. PRs should be merged to stage once they have at least 2 approvals and have verified or trivial label.
3. PRs to main branch should always be raised from stage branch.
4. Ideally while synching main from stage all the commits should be part of PR.
5. In urgent scenarios we can cherry pick a commit from stage and open a PR for main.
