Title: I exposed the variable 'network-bridge'' to allow users to specify to which network interface

the bridge should be bound to.

MAAS provider uses 'eth0' as the default network interface used to build the bridge br0, on some scenarios like LP: #1271144 (p1p2, eth2, ..) this assertion is not true.
