There are hardcoded values for IP addresses that are assigned to ports that the test creates. Address 10.0.0.3 collides with DHCP address in case there are at least two controllers in tested cloud with active/active DHCP enabled. (1. controller gets address 10.0.0.2 for dhcp port, second gets 10.0.0.3)

This leads to test failure when attempting to create port with 10.0.0.3 IP address because this address is already in use by the DHCP port.
