ogClient: add supported events to live mode

Live mode supports poweroff, reboot and boot events. This events serve
to send out-of-band requests to ogClient in order to run any of the
supported processes.

Live mode does not support any event datagram related to user session
notification.

XXX: Check if client is busy before processing the event.
