Add cosi.bucketClassParameters to allow passing arbitrary parameters
to the default BucketClass resource. This enables use cases like
tiered storage where a diskType parameter needs to be set on the
BucketClass to route objects to specific volume servers.
When bucketClassParameters is empty (default), the BucketClass is
rendered without a parameters block, preserving backward compatibility.
