Task Error propagation from agent

[HHeermann]

Agent needs to handle exceptions coming from

• adapter
• agent itself

Moreover in any case the payload that the agent returns will have this format:

{
“error”: false,
“statusCode”: 200,
“statusCodeReason”: “OK. Task status retrieved.”,
“message”: [
{
“taskId”: “048d4788-243f-4fa5-a9cd-02fe5c554077”,
“status”: “running”,
“createdAt”: “2018-10-04 14:13:16”,
“startTime”: “2018-10-04 14:13:17”,
“totalTime”: 255541,
“returnValue”: “{\n\t\”progress\“: 56\n}”
}
]
}

In case of error (status code!=200), “message” will be an empty array. In case of 200 status code, message will be the response coming from the adapter.
