whether he would like to become a super maintainer of the application. The
request is processed along with the application. Also add a unit test that
tests maintainer requests submitted along with an application.

a request has already been accepted, it is not a duplicate. Add a unit test to test the behavior of Maintainer::unQueue() on
an already unqueued maintainer.
