Description

Currently rgw dynamic resharding is almost unbounded. Yet we have evidence that more than 2000 shards can be problematic in some situations and we prefer their to be an odd number of bucket index shards. Allowing a maximum number of bucket index shards to be specified for dynamic resharding and favoring prime values would improve matters.
