Host can send required infos to the guest for performing forwarding.

Since forwarder_guest_launcher is not implemented in 100%, we should
manually run forwarder_guest_launcher with `--host-addr 192.168.0.1`,
and accessing `http://localhost:12345` to check the log printed at
forwarder_guest_launcher.

Bug: 340126051
Test: Manual test described above.
