MR template placeholder for the commit message body

Problem

Developers frequently manually copy/paste their commit message into the description box when creating MRs. This happens automatically only with MRs that don't have templates enabled.

Proposal

Add some kind of custom variable in the MR template settings where we can insert the commit message description within any part of the template.

Ideal solution

Template settings	MR form

MVC

Just insert the commit message right before the template content begins
