ChatOps for merge request
As a user, when I get assigned a merge request (MR) I get a slack notification that allows me to press merge.
The benefit is that if I already know that this is a good MR I can quickly merge it without having to go to another site and potentially having to login again.
This can be made with a Slack app https://medium.com/@MVaragnat/how-to-build-a-slack-app-5b83d71e083a
Future versions can be made to work for approvers too https://docs.gitlab.com/ee/user/project/merge_requests/merge_request_approvals.html
