Ability to disable automatically generated (pre-populated) title and description for a merge request
### Problem to solve
As a team-lead of a project, I have to review merge requests. Developers are frequently forget to make sure that title and description is correct. There should be a way to _force_ them to fill out all the fields from scratch, rather rely on automatically generated titles that does not always work as expected.
### Intended users
Development Team Lead will be very grateful when Developers actually use their brains to fill out the merge request.
### Further details
Just a checkbox in project settings to disable pre-populated titles and description for merge requests.
### Proposal
When team lead decides to disable pre-populated fields for merge requests - then developers will have to type something in.
### Permissions and Security
Same level of access to the checkbox as ability protect branches.
