Remove pips.

All of the requirements should now be specified in the pip-requires
of individual projects, which will be installed via setup.py install.

Therefore, remove the few remaining pip dependencies from devstack.

Distutils has a problem installing django 1.4 when django 1.3 is
already installed via debian packages.  Therefore, remove the
dependency on the django debian package (which installs 1.3
and is obsolete anyway).
