Attached disk usage monitoring

[DarinMacRae]

Is your feature request related to a problem? Please describe. I'd like to be able to monitor the disk usage of an attached data disk. The OS and user disks show up in the drop down but the attached data disks do not. I'd like those included too.

Describe the solution you'd like Attached data disks should show up in the drop down for monitoring disk usage on a node.
