Parsing error at AirflowWorkflowEngineServiceImpl class

Issue - getting parsing error while converting Airflow response JSON String into TriggerWorkflowResponse.java class

Reason - at the time of parsing it expects JSON string as per TriggerWorkflowResponse.java format. but This line collecting airflow response in the wrong format.

propose change -

replace the 141st line from AirflowWorkflowEngineServiceImpl.java with the following -

.responseBody(response.getEntity(String.class));
