After SWATCH-3927, there are still a couple of usages of the Subscription and Offering entities/repositories.  Specifically, there is an AccountResetService class that performs a delete of all subscriptions for an org.  There is no corresponding endpoint for this operation in swatch-contracts, hence the new card.

Acceptance:

• Coordinate with SWATCH Team 2 to create a deleteByOrgId endpoint for subscriptions.
• Remove subscriptionRepository.deleteByOrgId from the AccountResetService
• Use the new swatch-contracts endpoint in the IQE tests along with AccountResetService to perform the account reset.  E.g.

  •   swatch_tally_client.accountReset(org_id=123)
      swatch_contracts_client.contractsReset(org_id=123) 

• Remove all traces of usage for the Subscription, Offering, and related entities in swatch-tally.
