    fullstack: test for snat and floatingip

    Fullstack test to test snat and floatingip through legacy router.
    This test creates external network and boots a vm with external
    network's gateway and connected to central-external-br.
    Tenant vm is booted on internal network.
    Tenant Router is connected to internal and external networks.

    To test SNAT, it pings external vm from tenant vm.
    To test floatingip, a new floatingip is assigned to tenant vm
    and tests pinging to tenant vm's floatingip from external vm.
