[TASK] Optimize sending Topology Discovery message

[mariomaz]

After #1160, Topology Discovery message is sent on all operational network interfaces. To check for operational status, function network_utils::linux_iface_is_up_and_running() is being used. However, polling for the interface state is not efficient and an event-driven solution is going to be implemented in #1421. When available, replace the polling solution with the event-driven solution.
