## Problem
1. Users can't resync/rebase production branches but those could get
stuck too
2. We currently check for branches health state to allow resync/rebase,
preventing to unblock some cases
## Solution
1. Add an menu item to resync/rebase production branches
2. Remove the unnecessary health checks
