Implement REST GET /resources/{resourceId}

Implement REST GET /resources/{resourceId}
Should return the same thing as GET /resources/resourceGroups/{resourceGroupId}/releases/{releaseId} and additionally the name of the resource.

This calls should be removed and replace in the Angular UI:

• GET /resources/name/{resourceId}
• GET /resources/exists/{resourceId}

This is needed because GET /deployments/filter only returns the resource id of the application and there is now way to get more info on it:

        "appsWithVersion": [
            {
                "applicationName": "my_app",
                "applicationId": 270436,
                "version": "1.2.119"
            }
        ],

We could also add the release info to appsWithVersion to make it easier.

Was implemented as GET /resources/resources/{resourceId} to avoid overlapping paths. Returns the resource name, resource type and release name.
