Add App Roles (Active app) not providing expected response

[jjeroch]

While adding roles to an active apps via the API call POST:/api/apps/AppChange/${appId}/role/activeapp
the api response returns "success"

However if we now call the appRoles with
GET: /api/administration/user/owncompany/roles/apps/${appId}
the response is empty

[]

Check needed.
Tests executed on dev
Example app ID: a376f2c7-c5c9-46f6-96c8-4bafee3c2183

Please note: while analysing and fixing the issue; we should consider to move this endpoint to the app controller since this is connected to "apps". As soon as analysis of the issue is done; we should quickly align on the move of the endpoint

---

After analysing the ticket with Prasanna the following decision was made:
For the app provider an endpoint is needed to fetch the roles of an active app.
Till now we used an endpoint from administration service; but to ensure that we have a clear differenciation of the endpoints and services, we decided to create a own endpoint inside the app services.

Endpoint: /api/apps/{appId}/roles
Method: `GET``

Optional parameter: languagetag

Response Body

[
  {
    "role": "string",
    "descriptions": [
      {
        "languageCode": "string",
        "description": "string"
      }
    ]
  }
]

Validation: only active apps should be callable.

The endpoint provides requesters an overview of available app roles of active apps.

While adding roles to the active apps, if the api response for GET: /api/administration/user/owncompany/roles/apps/${appId}is [] and tried to add additional roles via POST:/api/apps/AppChange/${appId}/role/activeapp`, the post gets successful. Now, when GET api is called again, there should be roles available, but instead GET call responds with empty([]).

Tested in dev for appId: a376f2c7-c5c9-46f6-96c8-4bafee3c2183

As discussed with @jjeroch created an endpoint GET: /api/apps/AppChange/{appId}/roles to fetch the active app userRoles details.
