Ability to customize template for automatically created MR
### Problem to solve As a developer, when I create MR directly from issue, the MR description contains `closes #<issue_id>`. However, in our development flow after the MR is merged, we would rather add label to the issue. ### Further details It is possible to add merge request templates for MR created manually, but not automatically. ### Proposal Add support for `.gitlab/merge_requests_templates/mr_from_issue_default.md` ### Links / references
