There have been some lessons learned on how to best deploy glance from
using uwsgi in the gate. This commit updates the docs a bit to explain
some pitfalls to avoid.
This also adds a glossary at th end of the docs to explain common terms.
There are several very similar terms with related meanings used in the doc
so to clear up confusing the glossary should be helpful.

This commit adds docs and sample configs to glance for running glance
under apache. It also documents the limitations with the 2 common
methods of deploying wsgi scripts with apache, mod_wsgi and
mod_proxy_uwsgi, and why those don't work for the glance use case.
