> Unlikely other pagination APIs (list volume, bucket, keys, etc) snapshot diff 
> CLI help doesn't print default (or max) values for page-size.
> List bucket CLI help:
> {code:java}
> Usage: ozone sh bucket list [-hV] [--has-snapshot] [-p=<prefix>]
>                             [-s=<startItem>] [[-l=<limit>] | [-a]] <value>
> lists the buckets in a volume.
>       <value>               URI of the volume.
>                             Ozone URI could either be a full URI or short URI.
>                             Full URI should start with o3://, in case of 
> non-HA
>                             clusters it should be followed by the host name 
> and
>                             optionally the port number. In case of HA clusters
>                             the service id should be used. Service id 
> provides a
>                             logical name for multiple hosts and it is defined
>                             in the property ozone.om.service.ids.
>                             Example of a full URI with host name and port

>                             Short URI should start from the volume.
