quantum virtualenv doesn't build

[James E. Blair]

The quantum virtualenv doesn't build because SQLAlchemy is specified in both tools/pip-requires and the openvswitch/pip-requires, both of which are passed to pip when building:

    Remove plugin pip-requires.

    Fixes bug 906636.

    The cisco plugin included ncclient, but does not use it when testing.
    The openvswitch plugin included SQLAlchemy which is already required
    by quantum itself.

    I've also changed the install_venv.py script to only look at
    tools/pip-requires, so that it behaves more like the rest of the
    OpenStack projects. In Jenkins that's the only file we look at
    to see if we need to rebuild the virtualenv, so it would be best
    if the project only hade one pip-requires.

    Also added .gitignore to ignore files created during testing.
