nit: for the content API, we're using the recommended style for enums from the
chrome style guide (also matching WebKit API)

so this should be
enum QuotaPermissionResponse {
  QUOTA_PERMISSION_RESPONSE_UNKNOWN,
  QUOTA_PERMISSION_RESPONSE_ALLOW

you can name it QuotaPermissionContextResponse but that might be too long!
