1. New a thread to load detail info. Loading detail info takes too much time,
so the summary list and lineage can not be loaded timely.
2. Add a status for DetailCacheManager to indicate it is INIT, LOADING or DONE.
3. Update UT/ST.

For max processes used for computing, we need to make sure every summary directory has a process to load data. We also should not use too many processes to avoid system problems (eg. out of memory). So we calc the max processes cnt in _calc_default_max_processes_cnt

For _load_data_in_thread_wrapper, because self._load_data_in_thread() will create process pool when loading files, we can not afford to run multiple self._load_data_in_thread() simultaneously. So we use a lock to make sure that only one self._load_data_in_thread() is running.
