API flag to override approvers and approvals required per merge request

Zendesk ticket (internal link): https://gitlab.zendesk.com/agent/tickets/89093

A customer would like an API flag to override the approvers and approvals required per merge request.

This seems reasonable. There is currently an option to update the number of approvals with approvals_before_merge but I don't see one to override the approvers/approvals per MR.

Proposal

Add allow_override_approvals_before_merge or similar (type: boolean, required: no) to projects API replicating the behavior of the 'Can override approvals and approvers required per merge request' checkbox.

• POST /projects
• PUT /projects/:id
• GET /projects/:id
