As a developer, I'd like to refactor the billable usage producer to use swatch-common-configuration, so that I can retire tag_profile.

Note: billing window should be assumed to be monthly rather than looked up.

Done:

• The following classes contain no references to tag_profile:
  • BillableUsageController
  • RemittanceController no longer exists
  • TallySummaryMessageConsumer
  • ContractsController
  • BillableUsageMapper

QE Notes:
Tests : Remittance
