Warn if the source branch of a merge request is the target of open merge requests

Problem to solve

If the source branch of a merge request has pending merge requests, I probably want to wait for those to merge before merging the branch in it's current state.

Further details

Given this branch management process :

• team create a release-X branch
• each pair of dev create a feature-N branch
• each dev submit Merge Request to merge our work in release-X branch

When release manager submit the Merge Request from release-X to master branch

Then he would like to be warned that there are pending MRs from feature-N to release-X

Proposal

In the merge request interface, list any pending merge requests against the source branch.
