WifiConnectivityManager: partial scan only when connected
Starts partial scan only when Wifi is connected and traffic
is heavy. This is to work around an issue that WifiInfo
tx/rx rate is not updated to reflect the Wifi state. Ideally
the tx/rx rate should have been reset to 0 when Wifi is
disconnected.
Bug: 28831562
Change-Id: Ifa415b14e2b216654ddd8a2a0c885754da489bef
Test: Wifi Framework Unit Tests, manual tests
