virtualenv_name optoin doesn't make effect

Documentation says

If you would like to share a single virtualenv across topologies, you can set "virtualenv_name" in config.json which overrides the default behaviour of using the topology name for virtualenv.

I used it in conjunction with install_virtualenv set to false in order to use an existing virtualenv.
But unfortunately, it doesn't work - I inspected the worker's logs and found that it still used the topology name as the virtualenv name. I inspected the source of Streamparse and found that the virtualenv_name is not included into VIRTUALENV_OPTIONS in streamparse/cli/common.py and therefore it's not returned by resolve_options. The code calling resolve_options in streamparse/cli/submit.py assumes that virtualenv_name might be in the resulting dictionary.
