In order for swatch to communicate with the export-service, we want to use their openapi spec to generate swatch client code - like we do with other external services (subscription, entitlement gateway, product service, etc.)

Spec: https://raw.githubusercontent.com/RedHatInsights/export-service-go/main/static/spec/private.yaml 
https://editor.swagger.io/?url=https://raw.githubusercontent.com/RedHatInsights/export-service-go/main/static/spec/private.yaml 

Done:

• Export service is defined like https://github.com/RedHatInsights/rhsm-subscriptions/tree/main/clients

Testing:

• integration test the client via wiremock stubs
