Test that a parquet dataset saved in dataset format can be loaded and accessed using get_historical_features.

Steps:

• upload a parquet dataset to the test s3 folder
• point a source to the parquet dataset s3 folder (not the file)
• load the source features using get_historical_features

Ideally, there'd be a test for this running, but you'd be blocked on making a file within the Feast integration tests S3 bucket. Mind making an issue for that separately? @mzwiessele
