Overview

Given a plain source string, resolves which Fetcher should handle it and what key/path/url to pass to that fetcher's #fetch. This lets a single Loader mix HTTP, local file, and S3 sources in one call without the caller having to construct fetchers manually.

s3://my-bucket/path/to/en.yml -> S3Fetcher
http(s)://...                 -> HttpFetcher
anything else                 -> FileFetcher
