Task #7336: Give all temporary directories a suffix of the python file that created them, and clean up dangling temporary directories from tests

Task #7336: Allow method of feedback to be configured in pipeline.cfg, and create dedicated qpid queues at startup

Task #7432: Allow python lib to be imported even if HAVE_QPID is false, and keep an "enabled" member to track that

Task #7336: Forward QUEUE_PREFIX to outputProc as well, and corrected comments in MessageFuncs.sh (non-empty queues are also deleted on exit)

Task #7336: Never create queues by default (infrastructure should exist prior to software binding to queues). Testing framework added to create/delete queues with unique prefixes per queue. Fixed tests that used old queue names.

Task #7347: Provide complete feedback per file (now that the feedback does not stream through GPUProc to be augmented there)

Task #7336: Fixed FromBus.qpidMsg in python, use Message class everywhere, better logging in MessageRouter, set contenttype/durable on all messages

Task #7432: Added FindUUID, and generate timestamp + uuid for qpid messages (actually using Qpids own UUID functions)

Task #7432: Fixed FromBus::get, and added support for QUEUE_PREFIX environment variable (=an easy way to use dedicated queues in tests)

Task #7336: Remove SAS_Feedback from sas099 due to too many rollout issues (missing libpvss for PVSSGateway, missing generation of SASGateway.conf, etc)
