virsh: Add timestamps to QEMU monitor events

Browse Source 
Implement a --timestamp option for 'virsh qemu-monitor-event', similar
to the one for 'virsh event'.

When the option is used, the human-readable timestamp will be printed
before the message, and the timing information provided by QEMU will
not be displayed.
