Query values from SSM when deployed, by placing an SSM ARN as the environment variable
I wanted to query secrets from SSM at runtime, to laod them into a pydantic.BaseSettings settings object, but still be able to pass standard values during development (and I guess, if I want, in prod).
I've done a couple of similar implementations before, but they have always felt clunky and involved altering the object after instantiation, or hard coding which values to take out of SSM.
