mogzoneinfo review request

[GoogleCodeExporter]

mogadm check is great for seeing the overall picture but once you've got more 
than one zone splitting out how much space is available in each becomes an 
issue.

I used the check code as a start for the 'mogzoneinfo' command. It's output is 
similar but splits out the status and statistics (Disk space, etc) per zone 
instead of overall. I also subtracted out the min_free_space value in the 
available space calculation as it impacts the actual space mogilefs will use.

I find it useful - perhaps it can be included with the MogileFS::Network 
package if others do as well (or maybe integrated back into mogadm if everyone 
finds it useful)

Example output:

NOTE: SOME DEVICES SHOW NEGATIVE FREE SPACE AVAILABLE, THIS IS DUE TO THE 
'min_free_space' SETTING
    Current 'min_free_space' value = 48.828125 GB
