Improve NetworkServiceTestCase._get_ip_flow_range() function

Improve the method to calculate the CIDR IP address range (first one,
last one). IPv4Network or IPv6Network hosts() is an iterator throught
the list of valid IPs. If the network is too big, the generation of a
list [1] can be very expensive.
