#1061 add timeout to pending scheduled commands

Pending schedule commands can deny ogLive boot of clients due
to filling of pending cmd queue with commands such as "Iniciar Sesión".

For example: Using RemotePC to serve clients that do not boot into
ogLive will fill up the pending command queue with "Iniciar Sesión".

Introduce a safety timeout for pending (scheduled) commands to
avoid this situation.
