Payload with non serializable JSON data

[ajoaoff]

Original issue opened by @ArturoQuintana at kytos#138.

Hi, @cmagnobarbosa.
Issue 132 seems to be closed by PR 137, and in there, we referenced problems with some payloads.
The application continues failing in the case in which a payload specifies non-serializable JSON data.

some tests:

def test_030_install_flow_should_fail(self):
        """Test if the flow installation process specifying a
        wrong datatype payload behaves as expected (400 Error)."""

        payload = {
            "flows": [
                {
                    "priority"
                }
            ]
        }

        api_url = KYTOS_API + '/flow_manager/v2/flows/00:00:00:00:00:00:00:01'
        response = requests.post(api_url, data=json.dumps(payload),
                                 headers={'Content-type': 'application/json'})
        assert response.status_code == 400

def test_055_install_flows_should_fail(self):
        """Test if the flow installation process specifying a
        wrong datatype payload behaves as expected (400 Error)."""

        payload = {
            "flows": [
                {
                    "priority"
                }
            ]
        }

        api_url = KYTOS_API + '/flow_manager/v2/flows'
        response = requests.post(api_url, data=json.dumps(payload),
                                 headers={'Content-type': 'application/json'})
        assert response.status_code == 400

 def test_080_delete_flow_should_fail(self):
        """Test if the flow deletion process specifying a
        wrong datatype payload behaves as expected (400 Error)."""

        payload = {
            "flows": [
                {
                    "priority"
                }
            ]
        }

        # delete the flow
        api_url = KYTOS_API + '/flow_manager/v2/flows/00:00:00:00:00:00:00:01'
        response = requests.delete(api_url, data=json.dumps(payload),
                                   headers={'Content-type': 'application/json'})
        assert response.status_code == 400

def test_100_delete_flows_should_fail(self):
        """Test if the flow deletion process specifying a
        wrong datatype payload behaves as expected (400 Error)."""

        payload = {
            "flows": [
                {
                    "priority"
                }
            ]
        }

        # delete the flow
        api_url = KYTOS_API + '/flow_manager/v2/flows'
        response = requests.delete(api_url, data=json.dumps(payload),
                                   headers={'Content-type': 'application/json'})
        assert response.status_code == 400

@ArturoQuintana , what is the answer you are receiving? Your payload is really non-serializable, but as you try to serialize it prior to make the request, json.dumps call raises TypeError, so the call to kytos is never made.
To test this, you should try to pass the payload without serializing it first.
