KIP-463 — Auto-configure non-default Serdes passed alongside the TopologyBuilder

Discussion Streams

Fixes Kafka Streams to properly call `Serde.configure(Map<String,?> configs, boolean isKey)` on SerDes that are passed explicitly via `Consumed`, `Produced`, `Grouped`, etc., so user-provided SerDes receive the Streams application's configuration before use. The `configure()` method on explicitly-passed SerDes was either not called or called with an overwriting configuration that discarded the user's prior configuration, breaking SerDes that require application config at initialization.
