[Feature] Disk IO or Read/Write activity on a dashboard

[GAS85]

Description of the feature

Hey, really would like to see disk IO activity on a board as summery and per disk. I can already see it with simple iostat -m -z 2 command, e.g.:

docker exec dash iostat -m -z 2
Device:            tps    MB_read/s    MB_wrtn/s    MB_read    MB_wrtn
sdd               9.50         0.00         0.07          0          0
sdd3              9.50         0.00         0.07          0          0
dm-0             18.50         0.00         0.07          0          0
