Fix the S3 validation tests that broke during the data migration

[jgadling]

We did not update the S3 validation tests when changed the directory structure used by the portal's s3 bucket, so right now we're unable to validate that the output files/formats/structures of our s3 ingestion script are valid.

These validation tests need to be fixed:

• Update the json schemas to match our expected output formats
• Update the file paths expected by the validation tests to match our new spec
• Add support for alignments and per section alignment parameters to the tests
