Using BagDropService and DCS direct connection

Configuration and regular status checks while the SBD is idle is described here: Configuration and status checking.

It is possible for the SBD to have direct communication with a DCS, including through a broker, and only use the BagDropService for local configuration/information and transaction logging (BagNotify). The sequence diagram below shows the use of BagDropService in this setting.

The SBD is responsible for managing all aspects of the DCS communication.
