      Description

      In StreamingDataflowWorker, when setting the workId for the logging MDC, currently the code attempts to decode a binary blob as utf8.  This will (generally) cause a decoding error, and the java UTF8 decoder uses a globally synchronized cache to handle generating these error results.

      A simple solution would be to use the protobuf TextFormat escaping to convert the ByteString key into a string.
