autoserv: get transmitted/received byte counts at test beginning/end.
This adds to the autoserv log TX and RX byte counts obtained
from the network card on the DUT. It is done by adding a new
control segment, GET_NETWORK_STATS, which fails quickly if
the DUT is not immediately reachable.
Example output:
13:28:25 INFO | autoserv| get_network_stats: at-start RXbytes 56436340 TXbytes 109524115
...
13:28:42 INFO | autoserv| get_network_stats: at-end RXbytes 56595766 TXbytes 115204781
(this is from client/site_tests/hardware_DiskSize)
BUG=chromium:621319
