Add addTopic(List<TopicParams>)

New services are typically configured using TopicParameters.  These
are converted into Properties before being passed to
TopicEndpoint.addTopic(), which then converts them into BusTopicParams
before configuring a given topic.  Added
TopicEndpoint.addTopic(List<TopicParams>), which makes it possible
to configure the topics without going into the intermediate Properties.
Furthermore, because TopicParams is a subclass of BusTopicParams, no
conversion is needed for that either, so the TopicParams can be passed
directly into the configuration classes.
Incorporated changes from review.
