python: move qmp utilities to python/qemu/utils

In order to upload a QMP package to PyPI, I want to remove any scripts
that I am not 100% confident I want to support upstream, beyond our
castle walls.

Move most of our QMP utilities into the utils package so we can split
them out from the PyPI upload.
