Derbyshev Dmitry 200a40f94e qemu: expand domain memory statistics with 'last-update' timestamp 
QEMU reports timestamp along with other memory statistics, but this information is not saved into domain statistics.
It could be useful to determine if the data reported is fresh or not.
Balloon statistics are not reported in hrf, so no modifications are made in qemu_monitor_text.c.
