mon/Monitor: add "host" to tracked_conf_key

The get_tracked_conf_keys() method gets the specified keys
registered and works as filters for configuration changing,
so we can track these key configuration changing and react
properly.

Right now graylog prints host in its log entry, so
Monitor::update_log_clients() also reads from conf.host
and pass the host read from conf to graylog. That is
why we shall get "host" to the tracked_conf_key too.
