Fix network list and show with quantum.

The quantum driver was returning data in a format that was not
compatible with the extension. This munges the data and handles
fields that don't exist so the extensions still work.

Fixes bug 1076519

Documentation cleanups for nova devref

This patch contains a number of cleanups of the nova devref,
mostly related to outdated content.

1) remove outdated todo items from network
=> these have been long covered in the manuals

2) remove outdated multinic docs and images
=> this is now better covered in:
http://docs.openstack.org/trunk/openstack-compute/admin/content
/using-multi-nics.html

3) remove outdated cloudpipe docs, confs and scripts
=> This is now better covered in:
http://docs.openstack.org/trunk/openstack-compute/admin/content/
cloudpipe-per-project-vpns.html

4) remove outdated networking docs
=> These were marked as 'legacy' more than 2 years ago
