mgmt1: rethink firewall Admin API

Browse Source 
Handling each rule separately makes sense on from qvm-firewall tool
point of view, but not from overall configuration integrity. If multiple
tools try to configure firewall simultaneously, doing it at individual
rules level can end very badly.
So, get/set the whole firewall at once. If some race condition happen
here, it will end up with one firewall rules set being overwritten by
the other one. But it will still be a consistent rules set.
