AthenaConfiguration+AthenaPoolCnvSvc+OutputStreamAthenaPool: Add a new flag to mark streams temporary when applicable

This MR introduces a new CA flag, Output.TemporaryStreams, which holds a list of stream names that are marked by the user as temporary. If a stream is temporary, two things happen:

• We overwrite the compression settings to 101 (I kept ZLIB for forward/backward compatibility)
• We do NOT extend the provenance record

Tagging @gemmeren, @mnowak, and @maszyman explicitly for feedback.
