Raise hub-cleanup default batch size to 1000 for Hub 0.155.0

hub-cleanup deletes retention-expired documents by selecting a batch of ids
and deleting that id set. Larger batches amortize the id-selection
round-trip: in benchmarks a 1000-document batch roughly halved the selection
time versus 250, with no further gain above 1000. The chart always sets
BATCH_SIZE from `kerberoshub.cleanup.batchSize`, so the chart default is
what deployments actually run with.
