Prune development.environment doc
Prune development.environment doc

* Just point to dvstack docs
* Don't go into advanced tox features like '--notest' and how to source
  a env that tox builds. These are beyond setting up your environment.
  And are not very nova specific.
* Don't show how to build man pages, they are very out of date and
  mostly useless anyway.
* Drop 12.04 based install instructions
* We don't need libvirt-dev to run unit tests anymore
