Functest fail to parse tempest-based results

1. The regular expression can't work well for all tempest-based results
2. Refer to http://testresults.opnfv.org/test/api/v1/results?project=functest&case_name=refstack_defcore&last=1
3. There are 88 success test cases but the list of success is empty
4. tempest test case name is not always begin with {0}, it maybe any number
5. The test case whose name has the keyword 'fail' will also be list in 'failures'
