Revert case sensitivity feature due to performance degredation
Issue #, if available:
#9958
Description of changes:
A recent addition of a feature that adds case-sensitivity handling now lists out all files in the target directory prior to downloading during s3 cp calls. This results in a significant performance degradation when copying to large local directories as we now are listing all files in that directory and emitting warnings.
