    support reloctable venv roots in testing framework
    
    run_tests.sh, with_venv.sh, and the install_venv.py scripts now
    support relocating the venv root to another location.
    
    All 3 scripts now support new envinroment variables to configure
    the location of the venv and the tools directory. To maintain
    compatability the defaults are set to the current values.
    
    venv_path = Path to the venv root
    	Default: $(pwd)
    
    venv_dir = Directory that will contain the venv root
    	Default: .venv
    
    tools_path = Path to the tools directory
    	Defaukt: $(pwd)
    
    Additionally the run_tests.sh script also takes these value as
    arguments and will pass them along accordingly.
    
    --virtual-env-pathi <path>  Path to your virtualenv directory"
    --virtual-env-dir <dir>     Directory name for your virtualenv"
    --tools-path <dir>          Location of the tools directory"
