Stripping success result in order to speed up transmit in distributed test mode

Description

If the result is successful, fulfill SIZE information in BODY/HEADER etc, and replace DATA information with NULL. So the result could be smaller than it was.

Motivation and Context

When doing test in distributed mode, each Server will send its result back to Client. If the result size is big and the number of results is big too, it will take time to finish results transmition. Even we find that sometimes when test has already finished, STOP singal has been sent from Client to Servers, both Client and Servers cannot exit because result transmition was still undergoing whitch bocked Client and Servers from exting.
If a test result is FAILED, we do need its complete DATA information to do debug after test, we will not strip the result itself. But on the other hand, if a test result is SUCCESSFUL, we need only its SIZE to do static after test, we can trim all the DATA from BODY/HEADER etc.
