Run pipeline also in merge request
Problem to solve
Easy invocation of pipeline executions also directly in merge requests.
Further details
Currently only the pipeline page https://gitlab.com/gitlab-org/gitlab-ee/pipelines provides the Run Pipeline button. Then you have to choose your branch. But usually you're in our merge request and due to technical issues, you have to rerun the whole pipeline (as your artifacts might be already removed or the preparation job also has to run again). So it would be an improvement, if the Merge Request itself https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/7832 would also provide such a Run Pipeline butto, preselecting the correct branch.
Proposal
What does success look like, and how can we measure that?
Merge request page provides Run Pipeline button and clicking on that provides the Run Pipeline page, but with preselected branch.
