FEATURE: Make batch size configurable

To control the memory usage of single indexing jobs better the
batch size can now be configured via the:

    Flowpack:
      ElasticSearch:
        ContentRepositoryQueueIndexer:
          batchSize: 50

configuration setting. For backwards compatibility reasons a fallback
of 500 (the old hardcoded default) exists if the setting was not
configured at all.
