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.
