Deadlock when executing mqtt-tests

If you run
pytest .\dir\
the tests sometimes stops without any further progress.
After a short investigation it seems like tavern runs into a deadlock.
The problem seems to be that the paho-client uses another thread for executing the callbacks.
As a result the subscribe_lock of the client.py creates a deadlock

I've made a minor modification to the locks in #850 but I can't see anything else that could cause a deadlock. A related question, which version of paho-mqtt are you using? I know some people were having issues with the most recent version, you could try using version 1.5.0 or 1.5.1 and see if that works

This should be fixed in 2.0.5, if not then I suspect it's an issue in paho-mqtt
