    Fix race conditions in IP availability API tests
    
    DHCP port creation is asynchronous with subnet creation.
    Therefore there is a time window where, depending on how fast
    the DHCP agent honors the request, the DHCP port IP allocation
    may or may not be accounted for in the total number of used IP
    for the network. To kill the race, do not run dhcp on the
    created subnets at all.
