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.
This commit uses the approach used in jupyter_server #191 first proposed
by David Brochart. This reduces code duplication and alleviates redundancy
relative to configurable options.
Also, the startup message now includes the version information.

Eliminated the Kernel and Kernelspec handlers. The Websocket (ZMQ)
channels handler still remains. This required turning a few methods
into coroutines in the Notebook server.
Renamed the Gateway config object to GatewayClient in case we want
to extend NB server (probably jupyter_server at that point) with
Gateway server functionality - so an NB server could be a Gateway
client or a server depending on launch settings.
Add code to _replace_ the channels handler rather than rely on position
within the handlers lists.
Updated mock-gateway to return the appropriate form of results.
Updated the session manager tests to use a sync ioloop to call the
now async manager methods.
rather than initializing in main and starting in background, which seemed to cause occasional issues.
Also fix checking for dead notebook, which is no longer a subprocess.
