QPID-3936: Java Performance Test Framework - better PSFC support

Change ProducerParticipant to cancel the sending test messages after maximumDuration is reached.  This is required for
deterministic behaviour when using the Producer Side Flow Control feature of the Java Broker, otherwise the send() can
hang indefinitely after consumers have shutdown.
