Add CTS testing for ConnectivityDiagnostics Data Stall callback.

Browse Source 
Verify that onDataStallSuspected() is invoked by the System when
expected.

ConnectivityDiagnosticsManager provides an API for registering callbacks
with the System. These callbacks allow the System to notify registered
and permissioned callbacks on Network validation, suspected data stalls,
and Network connectivity reported.
