Timestamp hive partitions

[lauriemerrell]

Description

Refactoring GTFS schedule and Airtable to use timestamps in partitions instead of "time" strings.

Type of change

• Bug fix (non-breaking change which fixes an issue)
• New feature
• Breaking change (fix or feature that would cause existing functionality to not work as expected) -- we are doing a backfill so that the external tables will continue to work
• Documentation
• agencies.yml

How has this been tested?

Local Airflow.
