[Python] Asyncio-based Python Server

[kispaljr]

This is simply a feature request to add a new Python server generator that generates asyncio-based, or more precisely aiohttp-based webservers.
We already have a nice asyncio-based Python client generator, but I would also need a server-side counterpart for my asyncio-based projects.

This should be quite easy to add.
