    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 = Location of the virtualenv directory
    	Default: $(pwd)
    
    venv_name = Name of the virtualenv directory
    	Default: .venv
    
    tools_path = Location of the tools directory
    	Default: $(pwd)
    
    Additionally the run_tests.sh script also takes these value as
    arguments and will pass them along accordingly.
    
    --virtual-env-path <path>   Location of the virtualenv directory
                                 Default: $(pwd)
    --virtual-env-name <name>   Name of the virtualenv directory
                                 Default: .venv
    --tools-path <dir>          Location of the tools directory
                                 Default: $(pwd)
