/**
 * Mock Action Adapter for testing purposes. It simulates real action adapters on event bus.
 * Data exchange contract:

 * 
 * Input data Json Format
 *  *        {
 *          "clientRequest" : {..},
 *          "params" : {..}
 *        }
 *      
 * When clientRequest is the JSON representation of ClientRequest

 * And params is any JSON Object - currently not interpretted by mock
 
 * Output data Json Formt - is JSON representation of ClientResponse and additionaly `signal`
 * (String).

 * body field of the wrapper is suppose to carry on the actual response from
 * the mocked service (content of the mock file)
 In order to interpret response in the verticle
 * talking with mock, you can use following approach:

 *  *    new JsobObject(responseWrapper.getBody());
 *   
 * 
 *
