 * BrokerSingleton is a smart pointer to a process-wide singleton broker
 * started on an os-chosen port. The broker starts the first time
 * an instance of BrokerSingleton is created and runs untill the process exits.
 *
 * Useful for unit tests that want to share a broker between multiple
 * tests to reduce overhead of starting/stopping a broker for every test.
 *
 * Tests that need a new broker can create it directly.
 *
 * THREAD UNSAFE.
