We often call qmp() with unpacking dict, like qmp('foo', **{...}).
mypy don't really like it, it things 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 possing dict directly, simplifying interface, and giving a way to
satisfy mypy.

I guess it would have been nice to see some examples of this that can 
now be written in a cleaner way, but well.
