      Description

      Store the statePath as a basePath and a fileName and allow to overwrite the basePath. We cannot overwrite the base path as long as the state handle is still in flight and not persisted. Otherwise we risk a resource leak.

      We need this in order to be able to relocate savepoints.

      interface RelativeBaseLocationStreamStateHandle {
      
         void clearBaseLocation();
      
         void setBaseLocation(String baseLocation);
      
      }
      

      FileStateHandle should implement this and the SavepointSerializer should forward the calls when a savepoint is stored or loaded, clear before store and set after load.
