John Snow c63f3b0b29 python: add optional FUSE dependencies
In preparation for moving qom-fuse over to the python package, we need
some new dependencies to support it.

Add an optional 'fusepy' dependency that users of the package can opt
into with e.g. "pip install qemu[fuse]" which installs the requirements
necessary to obtain the additional functionality.

Add the same fusepy dependency to the 'devel' extras group --
unfortunately I do not see a way for optional groups to imply other
optional groups at present, so the dependency is repeated. The
development group needs to include the full set of dependencies for the
purpose of static analysis of all features offered by this library.

Lastly, add the [fuse] extras group to tox's configuration as a
workaround so that if a stale tox environment is found when running
`make check-tox`, tox will know to rebuild its environments.

QEMU Python Tooling
===================

This directory houses Python tooling used by the QEMU project to build,
configure, and test QEMU. It is organized by namespace (``qemu``), and
then by package (e.g. ``qemu/machine``, ``qemu/qmp``, etc).

``setup.py`` is used by ``pip`` to install this tooling to the current
environment. ``setup.cfg`` provides the packaging configuration used by
``setup.py`` in a setuptools specific format. You will generally invoke
it by doing one of the following:

1. ``pip3 install .`` will install these packages to your current
   environment. If you are inside a virtual environment, they will
   install there. If you are not, it will attempt to install to the
   global environment, which is **not recommended**.

2. ``pip3 install --user .`` will install these packages to your user's
   local python packages. If you are inside of a virtual environment,
   this will fail; you likely want the first invocation above.

If you append the ``-e`` argument, pip will install in "editable" mode;
which installs a version of the package that installs a forwarder
pointing to these files, such that the package always reflects the
latest version in your git tree.

Installing ".[devel]" instead of "." will additionally pull in required
packages for testing this package. They are not runtime requirements,
and are not needed to simply use these libraries.

Running ``make develop`` will pull in all testing dependencies and
install QEMU in editable mode to the current environment.

See `Installing packages using pip and virtual environments
<https://packaging.python.org/guides/installing-using-pip-and-virtual-environments/>`_
for more information.
