-Backports changes from PR to release branch.
-Requires multiple separate runs as part of the implementation.
-
-First run should do the following:
-1. Merge release branch with a first parent of merge-commit of PR (using 'ours' strategy). (branch: backport/{branch}/{pr})
-2. Create temporary branch over merge-commit to use it for PR creation. (branch: cherrypick/{merge_commit})
-3. Create PR from temporary branch to backport branch (emulating cherry-pick).
-
-Second run checks PR from previous run to be merged or at least being mergeable. If it's not merged then try to merge it.
-
-Third run creates PR from backport branch (with merged previous PR) to release branch.
