Allow a specific account under which new student assignment repositories should be created. #2557
Description
Proposed feature:
Allow a specific account under which new student assignment repositories should be created.
Background
I'm a TA at a course taught using Github Classroom. The classroom/course is owned by a Github organisation and I am one of four admins. I noticed that as students started working on the assignments, their repositories are created in my name (and that of other admins). Our Github accounts are used for the initial commits of the cloned repositories. This is annoying because it now shows up in my Github activity feed and because principally I did not really create that commit.
It might be hard/impossible to have creation be performed by the organization or student themselves. If so, I'd suggest allowing the assignment of a specific admin under whose account the new repositories get created (we can add a dummy TA account for this).
