Topic name prefix support added for Kafka

An enhancement has been added to support the use of site-specific standards for the naming of queues. This can be used to add clarification between Kafka Topics created by Pega and those created for internal topics when using a shared Kafka Cluster. This is done using the new setting: <env name=”services/stream/name/pattern” value=”prefix{stream.name}postfix”/> . As an example, if tenant.name is resolved into "myco" and the environment into "prod1", value="{tenant.name}-{environment}-{stream.name}" will result in stream myco-prod1-{stream.name} By default, when stream.provider = EXTERNAL, the default will be “pega-{stream.name}” .
