Sync venv scripts from oslo-incubator
Currently install_venv.py and with_venv.sh create virtual
environment in .venv directory and there is no way to specify
the virtual environment path explicitly.
This has been fixed in oslo-incubator.
This patch sync those virtual environment scripts from oslo-incubator.
Also make run_test.sh and run_tempest.sh scripts to use 'VENV' env variable.
