docs: // IsExtendedResourceName returns true if:
  // 1. the resource name is not in the default namespace;
  // 2. resource name does not have "requests." prefix,
  // to avoid confusion with the convention in quota
  // 3. it satisfies the rules in IsQualifiedName() after converted into quota resource name
