KAFKA-5142: Added support for record headers, reusing Kafka client's interfaces *This is still a work in progress and should not be merged.* This is a proposed PR that implements most of [KIP-145](https://cwiki.apache.org/confluence/display/KAFKA/KIP-145+-+Expose+Record+Headers+in+Kafka+Connect) but with some changes. The Kafka client library's `Headers` and `Header` interfaces are used directly so as to minimize the overhead of converting instances to a Connect-specific object. However, a new `ConnectHeaders` class is proposed to provide a fluent builder for easily constructing headers either in source connectors or SMTs that need to add/remove/modify headers, and a reader utility component for reading header values and converting to primitives. Note that KIP-145 is still undergoing discussions, so this is provided merely as one possible approach.
