Configure default "suggested change" commit message

Problem to solve

We have a regex which checks commit message to be in proper format. When I attempt to click Accept button on suggest an edit message, it errors out due to commit message is not properly formatted.

Steps to reproduce:

1. Set commit message regex in setting for a project.
2. Suggest and edit in merge request.
3. Attempt to click Accept button
4. 🤯

Proposal

Add a project setting to change the default suggested change commit message
