> List volume call can be used in three different contexts. One is for the 
> administrators to list all volumes in a cluster. Second is for the 
> administrator to list the volumes owned by a specific user. Third is a user 
> listing the volumes owned by himself/herself.
> Since these calls can return large number of entries the rest protocol 
> supports paging. Paging is supported by the use of prevKey, prefix and 
> maxKeys. The caller is aware the this call is neither atomic nor consistent. 
> So we can iterate over the list even while changes are happening to the list.
