Add new
 column
s into web UI:
> -- Block
Pool
Used 
>   the storage used for the block pool
> 
-- Block
Pool
Used
%
 
>   % of total storage used for that DN for the block pool.
> # Uses DFSUtil for percent calculation. Note that JSP had a bug where it reported, when
total was 0, percent used as 0 and percent remaining as 100. Rest of the code in namenode
node report percent used as 100 and remaining as 0 when total is 0.
> # Updated documentation ClientProtocol.getStats() method to reflect the new usage info
