   The metadata class is used in a lazy load implementation in
   QgsAuthMethodRegistry.  To save memory, auth methods are only actually
   loaded via QLibrary calls if they're to be used.  (Though they're all
   iteratively loaded once to get their metadata information, and then
   unloaded when the QgsAuthMethodRegistry is created.)  QgsProviderMetadata
   supplies enough information to be able to later load the associated shared
   library object.
