    Subclass must implement this method.
    If the device supports custom actions, subclass must add logic to take the necessary action.
    
    If the action attempt fails, the "rc" is set to 500 and the "message" field should be set accordingly, if the action is not supported, set "rc" to 501 and optionally set "message" accordingly
    
    Gateway must use the class CustomAction to retrieve the DeviceType and DeviceId for which the custom action request is received and act accordingly.
    
    Parameters:
    
    action - CustomAction where the device code can set the failure status and message
