v0.0.6

Rather than Request/Response => Map[String, String] instead prefer providing the entire context for addtional attributes (Request, Outcome[Option, Throwable, Response]) => Map[String, String]

Rather than removing headers keys not in the set, include them but redact the values.

What's Changed
