docstring: Get a storage instance for settings that will be saved in the "site" table.
  
  The storage will hold values that belong to the given idSite. Be aware that a storage instance for a specific
  site will be cached during one request for better performance.
  
  @param int $idSite   If idSite is empty it will use a backend that never actually persists any value. Pass
  $idSite = 0 to create a storage for a site that is about to be created.
  
  @param int $idSite
