**Description**
Fix bug of duration feature for model benchmarks in distributed mode.

**Major Revision**
- Add all_reduce to sync the result of is_finished(the function to judge whether the model benchmark should be stopped) in each step 
  - to avoid inconsistency between different ranks to determine duration end (some rank may enter one more step and can never finish)
- Add torch.cuda.synchronize() before and after step time measuring in train_step() for all model benchmarks
  - some operations in train_step() maybe async resulting incorrect step time records (for example, lstm) 

**Description**
Fix bugs in sync results on root rank for e2e model benchmarks.

Bugs:
 - results were not changed to sync results (grammer)
 - sync results not applyed to all ranks but only root rank
 - output result on local_rank 0 not global root rank

**Description**
Use config `log_raw_data` to control whether log the raw data into file or not. The default value is `no`. We can set it as `yes` for some particular benchmarks to save the raw data into file, such as NCCL/RCCL test.

**Description**
Please write a brief description and link the related issue if have.

**Major Revision**
- Sync (do allreduce max) the E2E training results among all workers.
- Avoid using ':0' in metric name if there has only one rank having output.

**Description**
Add 50th, 90th, 95th, 99th, 99.9th latency metrics for ORT and pytorch inference benchmarks.

__Description__

Add command `sb benchmark list` and `sb benchmark list-parameters` to support listing all optional parameters for benchmarks.

<details>
<summary>Examples</summary>
<pre>
$ sb benchmark list -n [a-z]+-bw -o table
Result
--------
mem-bw
nccl-bw
rccl-bw
</pre>
<pre>
$ sb benchmark list-parameters -n mem-bw
=== mem-bw ===
optional arguments:
  --bin_dir str         Specify the directory of the benchmark binary.
  --duration int        The elapsed time of benchmark in seconds.
  --mem_type str [str ...]
                        Memory types to benchmark. E.g. htod dtoh dtod.
  --memory str          Memory argument for bandwidthtest. E.g. pinned unpinned.
  --run_count int       The run count of benchmark.
  --shmoo_mode          Enable shmoo mode for bandwidthtest.
default values:
{'bin_dir': None,
 'duration': 0,
 'mem_type': ['htod', 'dtoh'],
 'memory': 'pinned',
 'run_count': 1}
