Docker networks do not get destroyed after execution/networks{} from networksActions.py is empty on new thread

After executing the yaml script, the docker networks are not destroyed. The containers themselves are destroyed correctly.

I assume this problem occurs from threading, so that every thread creates it's own instance of networksActions and the networks dict. I don't have enough Python experience to say for sure though.

Maybe a Singleton helps, if that is doable and good style in Python?

Update: This seems to occur only when I execute an own python script with the network simulator (eg in the yaml script). Still looking into it
