Permit Merge Request web interface to close a merge request as "merged with changes" with a positive-feedback color.
Problem to solve
The Merge Request Web Front-End should offer a way to "Close a merge request as merged", for instance, if the merge request had to be rebased or edited for integration.
It seems to be common for me, as software developer of a low-momentum open source project with volunteers in the community, when dealing with third-party contributed merge requests (from their forks) to rebase their requests because development has gone out of synch. I do this in order not to frustrate external contributors with too many requests to rebase/clean up their branches. However, the Web UI only permits me to "Close merge request", which several users appear to read as "rejected" -- and there is no way to flag them as "merged with changes".
Extend the web UI so there is an alternative way of "close merge request" as "mark as merged with changes" with green or yellowish-green colour.
