Remove inefficient saveListElementsBatch API

CpsDataService::saveListElementsBatch method is not needed as
saveListElements supports saving multiple list elements in a single
operation. This both simplifies implementation and greatly improves
performance when saving list elements, as the Yang parser need only
run once for the whole batch.

- Change InventoryPersistence to save CM-handles in batches of 100
  using existing CpsDataService::saveListElements method.
- Remove not needed CpsDataService::saveListElementBatch.
