Description

With KIP-71 (0.10.1.0) topic config `compact,delete` was introduce to apply to windowed store changelog topics in Kafka Streams. Later (0.10.2.0), session windows got added in KIP-94. However, session windows do not use `compact,delete` at the moment. This result is the same issue window stores face before KIP-71. Thus, we should enable `compact,delete` for session window changelog topics, too.
