This API was added a while ago and was never implemented: https://github.com/RedHatInsights/rhsm-subscriptions/blob/bbfd8e063e76bc16511a56f2d17c5d6d3e9e96aa/swatch-contracts/src/main/java/com/redhat/swatch/contract/resource/CapacityResource.java#L56

The tally resource from the monolith does use this API, but it's configured to not use the swatch contracts API, but the monolith API.

Moreover, the capacity API will be ported to swatch-contracts, so again, this API will be not needed.

Acceptance Criteria

• Remove unused capacity API from swatch-contracts
• Update the TallyResource to directly use the capacity controller
• QE: only regression testing
