Uploadcare integration with Ghost

@ErisDS, this is a working MVP! But in order to make it MLP (Minimum Lovable Product) one small thing is missing: this line above. I could not make it getting the value from the database: it returns a promise instead:

        {
            "key": "uploadcarePublicKey", 
            "value": {
                "fulfillmentValue": "hellothere", 
                "isFulfilled": true, 
                "isRejected": false
            }
        }


I could not turn the promise into a value. Can you help me with it?

Later on would be great to discuss how to turn it into a proper app.
