Create a virtual environment given some command line interface arguments.
:param args: the command line arguments
:param options: passing in a ``VirtualEnvOptions`` object allows return of the parsed options
:param setup_logging: ``True`` if setup logging handlers, ``False`` to use handlers already registered
:param env: environment variables to use
:return: the session object of the creation (its structure for now is experimental and might change on short notice)

Create a virtualenv session (same as cli_run, but this does not perform the creation). Use this if you just want to
query what the virtual environment would look like, but not actually create it.
:param args: the command line arguments
:param options: passing in a ``VirtualEnvOptions`` object allows return of the parsed options
:param setup_logging: ``True`` if setup logging handlers, ``False`` to use handlers already registered
:param env: environment variables to use
:return: the session object of the creation (its structure for now is experimental and might change on short notice)
