docs: // UnmarshalJSON overrides the logic for parsing the JSON-encoded
  // ContainerOverrides data
  // This custom unmarshaller is needed because the json sent to us as a string
  // rather than a fully typed object. We support both formats in the hopes that
  // one day everything will be fully typed
  // Note: the `json:",string"` tag DOES NOT apply here; it DOES NOT work with
  // struct types, only ints/floats/etc. We're basically doing that though
  // We also intentionally fail if there are any keys we were unable to unmarshal
  // into our struct
