message: Remove DeltaConnectionError telemetry
  Looking at code, prod telemetry and ODSP telemetry, this error duplicates Disconnected event and does not carry any more info than existing disconnected event. Also it's not really an error in a sense that it's expected condition, thus not worth having in error table.
