Add support for folder mounted Windows disks

[cruscio]

It appears disk/windows_disk.go filters on drive letters, excluding folder mounted volumes.

As a Telegraf user, I am looking to monitor all disk volumes mounted in Windows, both drive-letter mounted and folder-path mounted. Internally, Telegraf uses gopsutil to retrieve these data. Gopsutil appears to only support drive letters mounted disks.

Additional context

• Closed Telegraf bug: https://github.com/influxdata/telegraf/issues/8332

  • Expected behavior: When a volume is mounted to a folder in Windows, the [[inputs.disk]] plugin should output a series for that volume, with the path tag being the path to the folder mount point, and the device tag being either the volume DeviceId or the Disk & Partition numbers.
  • Actual Behavior: Only volumes mounted to drive letters are returned

• To help reproduce this issue without needing a physical device, one can create a small VHD and mount it to a folder. Some potentially helpful links:

@dloucasfx Is this being actively worked on? It would be great to have it fixed.
