rgw: raise default rgw_bucket_index_max_aio to 128

the maximum of 8 outstanding shard requests on a bucket index is an
unnecessary bottleneck, especially for CLSRGWIssueBucketList which
already has issues scaling to larger shard counts. the Objecter's
inflight ops throttle is already preventing us from flooding the osds
with requests
