The next test requires to setsockopt(TCP_CONGESTION) before connect(), so a new arg is needed for the connect_to_fd() to specify the cc's name. This patch adds a new "struct network_helper_opts" for the future option needs. It starts with the "cc" and "timeout_ms" option. A new helper connect_to_fd_opts() is added to take the new "const struct network_helper_opts *opts" as an arg.
