[ST01] Attributes data usage of test network by specifier

Currently, data usage of all test networks are all attributed to
the same NetworkIdentity, which does not allow services to
distinguish upload & download traffic of different test networks.

Thus, this CL put specifier that comes along with
TestNetworkAgent into wifiNetworkKey field to build different
NetworkIdentity to attribute data usage to different for
individual networks. And allow querying test network usage with
wifiNetworkKeys.
