Feat: pick labled MRs into autodeploy branches

When there are severity::1 issues that exist in the projects, all jobs of creating auto-deploy branches will be blocked, and thus the subsequential deployments are stopped because there are no new commits/versions in the auto-deploy branches. Then we will step into the process of bug fix.

To make sure all bugfixes are verified in staging environment before finally being deployed into production, we need a mechanism that picks the bugfixes into the current auto-deploy branches.
