Fix hadoop short circuit reading can not enabled in some environments.
- Revert #21430 because it will cause performance degradation issue.
- Add `$HADOOP_CONF_DIR` to `$CLASSPATH`.
- Remove empty `hdfs-site.xml`. Because in some environments it will cause hadoop short circuit reading can not enabled.
- Copy the hadoop common native libs(which is copied from https://github.com/apache/doris-thirdparty/pull/98
) and add it to `LD_LIBRARY_PATH`. Because in some environments `LD_LIBRARY_PATH` doesn't contain hadoop common native libs, which will cause hadoop short circuit reading can not enabled.
1. fix concurrency bug of s3 fs benchmark tool, to avoid crash on multi thread.
2. Add `prefetch_read` operation to test prefetch reader.
3. add `AWS_EC2_METADATA_DISABLED` env in `start_be.sh` to avoid call ec2 metadata when creating s3 client.
4. add `AWS_MAX_ATTEMPTS` env in `start_be.sh` to avoid warning log of s3 sdk.
Optimize the usage of fs benchmark tool:
1. Remove `Open` benchmark, it is useless.
2. Remove `Delete` benchmark, it is dangerous.
3. Add `SingleRead` benchmark, user can specify an exist file to test read operation:
`sh bin/run-fs-benchmark.sh --conf=conf/hdfs_read.conf --fs_type=hdfs --operation=single_read`
4. Modify the `run-fs-benchmark.sh`, remove `OPTS` section, use options in `fs_benchmark_tool` directly
5. Add some custom counters in the benchmark result, eg:
```

- For `open_read` and `single_read`, add `ReadRate` as `bytes per second`.
- For `create_write`, add `WriteRate` as `bytes per second`.
- For `exists` and `rename`, add `ExistsCost` and `RenameCost` as `time cost per one operation`.
