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. Change-Id: Id87e2c6812e36ae1a3ac680e6b35208667971782 Issue-ID: POLICY-1953 Signed-off-by: Jim Hahn <jrh3@att.com>
