Merge ~cjwatson/launchpad:redistribute-faq into launchpad:master

[Colin Watson]

Remove FAQ and redistribute its contents

Daniele Procida's opinion was that FAQs are an antipattern in documentation, essentially (I think) because they tend not to actually be what's frequently asked. It would make more sense to distribute the material here into other relevant pages anyway, so do so.

I omitted "What version of Python is required?" entirely, since that's already covered near the top of `doc/how-to/running.rst`.

[Jürgen Gmach (jugmac00)]

I certainly agree with Daniele here, and I try to convince the other maintainers of tox also removing the faq section, which by far - is no faq section.
