netipmid: move event loop to boost::asio::io_context

Replacing the event loop with asio provides for more flexibility and
less code than the sd_event model. Intially, this will require the loop
to handle both sd_events with a wrapper, but after all the sd_event
sources are replaced with asio event sources the wrapper can be removed.
