Trim some cloud tests.

[delucchi-cmu]

Change Description

Addresses the first few objectives on issue #175.

• the data hosted in abfs has been updated with the new _metadata files, and doesn't have any partition_info.csv files
• updated script to only copy the /tests/data directories that are used in cloud_tests tests.
• I took out most of the tests, since we're exercising the same code multiple times, and in many cases, not adding coverage for cloud-specific behavior.
• black/isort/pylint (adds directory to pre-commit check)
• remove some of the dead code, particularly in conftest files
• uncovered an issue with path construction in _metadata for cloud-based parquet Dataset (the path is munged in the dataset construction, but not re-munged when we strip out the prefix for the file-level path).
