Feature request: support for Yaml column renaming

A user already expressed interest in this feature for renaming columns coming from apis as hashes.

This would be an easy way for a user to reconfigure field names already listed to them, instead of them having to figure out the names upfront in python.

This is an overlap with the previously discussed name mapping via the schema for long column names for databases with short names support such as Postgres.

No files, tests, or entry points are identified in the issue. Start by locating the schema and YAML configuration handling, then determine how API hash fields and database column mappings are represented; done means users can reconfigure listed field names through YAML without determining the names upfront in Python, while accounting for the existing schema name-mapping discussion.
