Feat(fulfillment): service provider registration + fulfillment management (#6524)

**What**
- Create the fulfillment manual package with a first iteration API 
- Create a new `AbstractFulfillmentProviderService` and `IFulfillmentProvider`
- Modify the module service interface to add new methods to manipulate the fulfillment and the communication with the external provider
  - create (no bulk)
  - cancel (no bulk)
  - update (no bulk)
  - list
  - listAndCount
  - retrieve
- Add new methods to the service provider service to include communication with the third party provider
  - get options
  - create
  - cancel
  - validate data
  - validate option
- Update/create interfaces and DTO's
- fix repository serializer to allow non entity to be passed without throwing
- split module tests into multiple files to simplify navigation
- Add integration tests to validate fulfillments manipulation and external provider loading + communication
