[Twisted-Python] Adding support for Diameter protocol

[Hamza Sheikh]

I am new to Twisted and its community and exploring adding Diameter 
support. I have experience with Python but as I learn more I realize how 
little I know. This is my first foray contributing to a real open source 
project. I'm basically looking for mentors to guide me when I have 
questions about:

* Async code
* Wiring code to support both Python 2.x and 3.x
* Style guides
* Other things

If dedicated mentors are hard to come by I'd be grateful for this ML to 
help with answers. Looking forward to working with the community on a 
great project.
