RESTapiCallNode make request without content-type

currently the RESTAPI adaptor doesn't make a REST request with empty Content-type, this change is to help the adaptor to make request with no Content-type, currently defaulting to application/json. This is to avoid, when some servers throw 415 Unsupported Media Type error, when they dont support JSON response.
