Network driver should allow connecting to a bssid #2144
Description
In some network scenarios multiple access points can share the same ssid, in these cases it may be useful to allow specifying a bssid rather than an ssid, to allow connecting to a specific access point. An addition benefit of specifying the network access point by bssid is that generally this will speed up network connections, since the ESP-IDF driver will stop scanning as soon as the bssid is found, when scanning by ssid, the driver will look for additional bssids using the same ssid.
