API call /maintenance/{mw_id} on PATCH is returning misleading response status

[ArturoQuintana]

• The action to PATCH a payload where the items field is empty is returning 201 when it should be 400.

Example: payload1 = { "start": start.strftime(TIME_FMT), "end": new_time.strftime(TIME_FMT) } mw_api_url = KYTOS_API + '/maintenance/' + mw_id request = requests.patch(mw_api_url, data=json.dumps(payload1), headers={'Content-type': 'application/json'})

• The action to PATCH a payload with no items field is returning 201 when it should be 400.

Example: payload1 = { "start": start.strftime(TIME_FMT), "end": new_time.strftime(TIME_FMT) } mw_api_url = KYTOS_API + '/maintenance/' + mw_id request = requests.patch(mw_api_url, data=json.dumps(payload1), headers={'Content-type': 'application/json'})

• A PATCH action using a not serializable JSON broke the application, and it should return a 400 error.

Example: payload1 = { "description" } mw_api_url = KYTOS_API + '/maintenance/' + mw_id request = requests.patch(mw_api_url, data=json.dumps(payload1), headers={'Content-type': 'application/json'})
