    Use different CIDRs for private and public subnets
    
    In test "test_connectivity_dvr_and_no_dvr_routers_in_same_subnet", as
    reported in the bug, the public IP (floating IP) and the private IP
    are in the same CIDR. This breaks the isolation between networks.

Title:
  [Tempest] Floating IP and static IP should be in different CIDRs

Status in neutron:
  Fix Released

Bug description:
  In "test_connectivity_dvr_and_no_dvr_routers_in_same_subnet", both the
  floating IP and the static IP are in the same CIDR. This implies the
  GW for both subnets is the same and the traffic can't be router
  properly.

  We should check first the external network CIDR and assign a non
  overlapping one to the private subnet.
