test_result_verifier.py attempts to normalize error messages so that they may be compared against expected results. This involves removing hdfs qualified paths which may vary, e.g. because they include a hostname.
This won't work for s3, we need to generalize this normalization mechanism so that it doesn't rely on hdfs paths and also so that it does not encode specific knowledge of error messages.
After doing so, remove tests marked with @skip_if_s3_qualified_path.
