The client is able to be run as a monitor to connman. When connmanctl is
started with the monitor option, it will wait for any signals from connman
and display them in the terminal. It is useful if one wants to have some
realtime verbose output of connman, and how it reacts to various input,
e.g setting ipv4 to use dhcp.
