docs: // ExtractFieldPathAsString extracts the field from the given object
  // and returns it as a string.  The object must be a pointer to an
  // API type.
  //
  // Currently, this API is limited to supporting the fieldpaths:
  //
  // 1.  metadata.name - The name of an API object
  // 2.  metadata.namespace - The namespace of an API object
