When Tempest is used in customer site, often we are required to provide a testcase list including testcase names and descriptions. Now no this kind of doc is available, so we can add descriptions with the format of doc string for every testcase, so later we can generata such a testcase description list. There are hundreds of testcases missing descriptions, so we can add them gradually, and limit the modified files in one patch for the convenience of reviewing.
