Default failed response handler

Default failed response handler

In a service factory setting up the request fail handler is optional, and in case we dont specify a fail handler a default one will be used, the default response handler from domino-rest will just log the exception. we can override the default fail handler using DominoRestConfig.

DominoRestConfig.getInstance()
    .setDefaultFailHandler(failedResponse -> {
        //do something for a failed request that did not specify a fail handler.
    });
