dovetail tool: bugfix: test cases are erroneously judged

JIRA: DOVETAIL-375
JIRA: DOVETAIL-390

1. defcore test cases are erroneously judged because of:
   a) defcore results json data lack some keys
   b) some sub-testcases' names are the same as the prefix of another sub-testcases.
2. this patch removes the extra keys and judge sub-testcases accurately.
3. remove "store_type" in functest_config.yml and yardstick_config.yml.
4. change some log levels from info to debug.
