/bin/wifi: setclient performance improvements.
Use wpa_cli reconfigure rather than stopping and starting
wpa_supplicant. This makes associating with a new AP much faster.
The total /bin/wifi time to reassociate is now ~3 seconds, down from
10-15. Most of this is /bin/wifi itself, but reassociating can still
take ~1s.
If an AP is running as well, it will still take time to stop and
restart that, but once b/30140131 is resolved we may be able to remove
that as well.
