Bug 1361732 - Mozharness support for a second virtualenv using python3; r=aki Currently Mozharness creates a Python 2.7 virtualenvironment with all the packages needed for Mozharness to run plus any applications that need to execute within it. For Talos, we now need a second Python virtual environment for mitmproxy, however, this package is for Python 3 and not for Python 2 (perhaps it could have worked). In any case, having the ability to support create Python 3 virtual environments will be handy. Specially since the approach of creating virtual environments is not by using 'virtualenv /path/to/venv' but by calling the venv module like 'python3 -m venv /path/to/venv'. The initial implementation only supports a list of modules. The following iteration will support requirement files and other parameters needed for pip and internal pypi hosts.
