Determines the {@link RedundancyStatus} for the region. If redundancy is not configured (i.e.
configured redundancy = 0), this always returns {@link RedundancyStatus#SATISFIED}.

@param desiredRedundancy The configured redundancy of the region.
@param actualRedundancy The actual redundancy of the region.
@return The {@link RedundancyStatus} for the region.
