[PATCH v4 26/35] python/qemu/machine: QEMUMachine: improve qmp() method

[Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com>]

We often call qmp() with unpacking dict, like qmp('foo', **{...}).
mypy don't really like it, it thinks that passed unpacked dict is a
positional argument and complains that it type should be bool (because
second argument of qmp() is conv_keys: bool).

Allow passing dict directly, simplifying interface, and giving a way to
satisfy mypy.
