  1. update trace replay mode for post analysis (facebookresearch#20) 

    Summary:
Pull Request resolved: facebookresearch#20

- Output new traces with sequence number and latency for post analysis (one file per rank since there could be skew due to imbalanced workloads)
- Remove extra barrier in non-blocking mode
- add option `--allow-list`/`--allow-ops` to specified desired collectives to be replayed and ignore the rest in the trace
- cleaner summary output in the end (move to logging.info)
- Add workaround to correctly complete UCC collectives in non-blocking mode
