Point the .NET client at the StreamAlarms alarm feed

Browse Source 
Replace the client's QueryActiveAlarmsAsync with StreamAlarmsAsync —
a session-less subscription to the gateway's central alarm feed that
yields the active-alarm snapshot followed by live transitions.
AcknowledgeAlarm is session-less (AcknowledgeAlarmRequest no longer
carries a session id). Updates the transport interface, the gRPC
transport, the test fake, and the alarm tests; the .NET client
solution builds and its alarm tests pass.
