Add HTTP request and response handler attributes to Http Task of Flowable Modeler

Hello team,
There is a way to handle http request and http response by custom handlers.
Please add the ability to define the handlers in the flowable modeler.

Thanks,
Harsha

Start in the Flowable Modeler implementation of the HTTP Task and trace how HTTP request and response properties are currently represented. Determine the intended configuration for custom request and response handlers; done means both handler attributes can be defined and persisted in the modeler.
