KIP-276 — Add StreamsConfig prefix for different consumers

Accepted Kafka 2.0 StreamsConsumer

Adds main.consumer., restore.consumer., and global.consumer. config prefixes to StreamsConfig, allowing users to set different config values for each of Kafka Streams' three internal consumer clients. Streams previously used a single consumer. prefix shared by all three consumers, making it impossible to tune fetch sizes, session timeouts, or security settings independently for restore vs main consumption.
