On systems that don't use devstack the nova directory doesn't automatically get added to the python path. This breaks tools/install_venv_common.py which imports from nova.openstack.common. This fixes the issue by manually adding the nova root directory to the python path before tools/install_venv_common.py is imported. Change-Id: I8a3df02a51c2c777d8f47cb8bc72d0644ae47095
