Title:
  Gateway IP is overlapped when using one brigde for two network on
  FlatDHCP mode

Status in OpenStack Compute (Nova):
  Invalid

Bug description:
  On FlatDHCP mode, I can create two networks with same bridge name, then the gateway IP is overlapped.
  There is no sanity checks for this.

  The way to avoid this is forbid to create two networks with one bridge
  or smart to judge to avoid gateway ip overlap.
