[improvement] Remove experimental feature with ShuffleUploader

[colinmjj]

What changes were proposed in this pull request?

ShuffleUploader is an experimental feature which is target to merge and upload data from local disk to remote storage if local disk hasn't enough space. It is replaced by MEMORY_LOCAL_HDFS and should be removed to avoid maintenance in the future.

Why are the changes needed?

The experimental feature is redundancy and we have to maintain it during update with new features about storage.

Does this PR introduce any user-facing change?

No

MultiStorageFaultToleranceTest have a useful case hdfsFallbackTest. We shouldn't remove it. It verify that we can write data to local disk, when we fail to write data on hdfs.
