[PATCH 1/4] python/aqmp: add explicit GPLv2 license to legacy.py

[John Snow <jsnow@redhat.com>]

The legacy.py module is heavily based on the QMP module by Luiz
Capitulino (et al) which is licensed as explicit GPLv2-only. The async
QMP package is currently licensed similarly, but I intend to relicense
the async package to the more flexible LGPLv2+.

In preparation for that change, make the license on legacy.py explicit.
