Add documentation about deploying Django under SCGI and AJP

[vizualbod]

1. This document primarily focuses on FastCGI. Other protocols, such as SCGI and AJP, are also supported, through the flup Python package.
2. Before you can start using FastCGI with Django, you’ll need to install flup.

Do I need flup for FastCGI or is it just needed to use SCGI and AJP? The first note needs reformulate.

It would be also good to add a few notes about Django + CherryPy WSGI server + Nginx as a proxy.
I can provide some materials for this if there is interest as I find it a rock solid setup better than mod_python.

I'm not sure we need to exhastively document deploying Django in all the various ways it could be done, but if someone writes a SCGI, AJP, or whatever doc there's no reason not to include it.

It suddenly strikes me that requesting a guide for a specific deployment strategy is much like requesting a translation, and Jacob's answer would be every bit as true if he were talking about the local dialect rather than server technologies.

Thereby it seems reasonable to hold a similar policy: tickets should be opened when a deployment guide is provided, not when one is requested (see Russ' succinct answer on #13286).
