shill: WiFiProvider: Emit metrics for remembered WiFi Services
Whenever a profile is loaded, emit an UMA metric indicating how
many WiFi services are now configured by a non-ephemeral profile.
This will allow us to maintain statistics on how many WiFi
services users tend to have at once.
BUG=chromium:396785
TEST=Unit tests + manual: restart shill while logged in, browse to
chrome://histograms and note there are now two (more)
"Network.Shill.RememberedWiFiNetworkCount" metrics -- one when the
default profile was loaded, and one for when the user profile
loaded.
