[PATCH 00/20] python/qemu: strictly typed mypy conversion, pt2

[John Snow]

Continuing where I left off prior to the 5.1 release, this series
touches up a few odds and ends and introduces mypy hints.

What's new:

- Using isort to solidify import order
- Patches adding small corrections and typing for console_socket
- A few error class changes for qmp.py

Like my QAPI series, this requires:

- pylint >= 2.6.0
- flake8 >= 3.8.0
- mypy >= 0.770
- isort >= 4.3.0 (Presumably...)

What this series doesn't do:

- Create a proper python package
- Establish a CI test to prevent regressions
- Fix the docstring conventions in the library

Those are coming soon! (and in the order mentioned.)

5.1:
