> long quotaInBytes are new fields in the bucketArgs, this field will go to 0 
> by default in the old bucket when the old cluster is upgraded. At this point, 
> the data writes are rejected.
> This is similar to creating a bucket without specifying quotaInBytes, where 
> quotaInBytes is set to -1 by default via getQuotaValue. We can use 0 as a 
> special term.
