Rob Mulholand b8fec5e4e3 (VDB-929) Minimize storage key lookup bespoke code
- Extract shared namespace for looking up and hashing keys
- Require storage transformers only to implement a loader that
  associates known keys with metadata
- Move key loader/lookup utils to utils directory to avoid
  multiple "storage" packages in imports
