Send topics on the semantic component by creating/modification/deletion of a use case

[darya-mart]

When a use case on the marketplace is created/modified/deleted send a topic with the corresponding body on the semantic-services component.

Previously discussed example model:

 {  
   "id": "27e2b7b9-05a4-4f4f-b071-875ccb524cb7",
   "title": "Test Use Case",
   "shortDescription": "Please enter a short description statement of the use case",
   "description": "Please enter a description statement of the use case",
   "approach": "Use Case approach",
   "status": "INITIAL",  possible values [INITIAL, PUBLISHED]
   "industries": 
       [
        {
         "label": "Healthcare",
         "uuid": "http://planqk.de/ontologies/qco/data/Healthcare"
        }
      ],
   "applicationAreas": 
       [
        {
         "label": "Medical Informatics",
         "uuid": "http://planqk.de/ontologies/qco/data/e076a698-e1f4-4c65-825e-6e88ba6a4602"
        }
      ]
 }

IMHO this can be closed due to the latest changes.
