ARROW-5877: [FlightRPC] Fix Python<->Java auth issues - Java servers before didn't actually wait for the Handshake RPC to complete - Java servers didn't interrupt auth handlers if the client sent an error - Python/C++ clients didn't explicitly finish their end of the connection Together, this led to the 'hanging forever' issue @rymurr saw. I've left some TODOs as I would like to raise Flight-specific exceptions (which I'm working on in parallel).
