/**
 * CauseFailure provides a method to cause a failure in a messaging broker, usually used in conjunction with fail-over
 * or other failure mode testing. In some cases failures may be automated, for example by shutting down an in-vm broker,
 * or by sending a special control signal to a broker over a network connection. In other cases, it may be preferable
 * to ask a user interactively to cause a failure scenario, in which case an implementation may display a prompt or
 * dialog box asking for notification once the failure has been caused. The purpose of this interface is to abstract
 * the exact cause and nature of a failure out of failure test cases.
