In upstream Avocado, the find_free_port() function is not available from "network" anymore, but must be used via "ports", see: https://github.com/avocado-framework/avocado/commit/22fc98c6ff76cc55c48 To be able to update to a newer Avocado version later, let's use the new way for accessing the find_free_port() function here.
