* CSW Harvester / Avoid increment 2 metrics for a single metadata in certain conditions.

Retrieve metadata method increments metrics under certain conditions and returns null. Methods calling the retrieve metadata method increments additionally the unretrievable metric if null is returned. Sonarlint fixeas are already applied. Fixes geonetwork#8039

* CSW Harvester / Use primitive boolean for 'force' parameter
