Open Stack

Replying to myself:
It was fixed by adding environment variables to the magnum-conductor service:

[Service]
Environment="HTTP_PROXY=http://<HOST>:<PORT>"
Environment="HTTPS_PROXY=http://<HOST>:<PORT>"

Now I'm waiting for the first cluster to be created, the first  
resources were created successfully, now it seems stuck. But that's a  
different issue, this one can be considered resolved.

Thanks,
Eugen
