This commit updates the super usage. Because Python 2 is not supported
anymore, super usage can be updated such that super is called without
any arguments in the default case where super is called with the class
name and self.
Note that all usage of super has not been updated - a few cases which
smelled funny have been ignored.
instead of the monkeypatch we did to keep the backport patch small
requiring tornado 5 simplifies things a ton because tornado.concurrent.Future is asyncio.Future
