1. Change "time" to "duration".
Because "time" and "times" are too close, and have
different meaning in rally. While, "duration" is much cleaner,
has only one meaning that means actually what we have in results.
2. Change "atomic_actions_time" to "atomic_actions"
Because not only "time" include in this column, and we already
have "duration" inside it.
3. Similar changes for functions and class members
