Comments:
- JSON (Rally) files parsing is ready and can be used in a jiffy.
- CSV parsing is good, but you must follow original format:
- no heading
- csv lines: XX,test,<result>,<message>,...
- CLI parsing is tricky, remove all config and other subunit 'env' stuff. Leave string starting as tempest....
- XML (PyCharm) parsing should work.
