Some cloud APIs operate at a conceptual "site" level, where each API request returns data for all "devices" within the site. In this scenario, each device should be represented by unique SN source IDs. Cloud datum stream configurations currently assume a single source ID is used for the generated datum, however. This ticket is to loosen this restriction so that a single cloud datum stream configruation can produce datum for any number of source IDs.

One approach might be to allow placeholders in the cloud datum stream source ID value. This would thus not require any data model changes in the Cloud Integrations system.
