Document that GetNextBid is not used in QoS calculations

[hrosenbe]

The getNextBid operation is not used when determining whether the workload has passed the response-time QoS requirements. This is because the GetNextBid operation is asynchronous and its response-time varies greatly depending on the bidding rate. As a result, the run summary in the run-*.log files currently reports a Pass RT percent of 0 for this operation, which will be confusing to users.

We need to:

• Update Section 6.5 of the Users Guide to explain that GetNextBid is not used for response-time QoS.
• Change the run-*.log output to reflect this fact, but in a way that doesn't disrupt scripts that rely on post-processing this file. That probably means leaving the 0 but adding a note in the file.
