Feature Request: query storage uses for all storage

[og900aero]

It would be nice if you could request the use of all disk space at once. This would allow you to see the data of all disks in one place.
Example

./check_pve.py -k --username monitoring@pve --password xxxxxxxxxxx --api-endpoint 172.16.1.3 -m storage -n pve01 -w 80 -c 90

And Icinga show:

OK - Usage of storage 'local-zfs' is 14.76%
WARNING - Usage of storage 'ha-pool' is 65.09%
OK - Usage of storage 'local' is 12.11%
OK - Usage of storage 'ssd' is 41.41%

./check_pve.py -k --username monitoring@pve --password xxxxxxxxxxx --api-endpoint 172.16.1.3 -m storage -n pve01 -w 80 -c 90 --ignore-disk local,local-zfs

WARNING - Usage of storage 'ha-pool' is 65.09%
OK - Usage of storage 'ssd' is 41.41%

I will give it a thought, but can't promise anything at the moment
