Filesystem plugin: Add "EncryptionStatus" to each volume on Windows

[stuartpreston]

Description

On a Windows System (tested on Windows 10), the EncryptionStatus for a volume can be seen by inspecting the win32-encryptablevolume class in the root/cimv2/security/MicrosoftVolumeEncryption namespace or by executing the following PowerShell (full compatibility/module versions to be determined)

> (Get-BitlockerVolume -MountPoint "C:").VolumeStatus
FullyEncrypted

Using this information would enhance the ohai filesystem plugin output to look similar to the following:

{
  "C:": {
    "kb_size": 511463911,
    "kb_available": 252410994,
    "kb_used": 259052917,
    "percent_used": 50,
    "mount": "C:",
    "fs_type": "ntfs",
    "volume_name": "",
    "encryption_status": "FullyEncrypted"
  }
}

The encryption_status field is the text representation of the ConversionStatus class from https://docs.microsoft.com/en-us/windows/desktop/secprov/getconversionstatus-win32-encryptablevolume#parameters:

Value	Meaning
FullyDecrypted	For a standard hard drive (HDD), the volume is fully decrypted. For a hardware encrypted hard drive (EHDD), the volume is perpetually unlocked.
FullyEncrypted	For a standard hard drive (HDD), the volume is fully encrypted. For a hardware encrypted hard drive (EHDD), the volume is not perpetually unlocked.
EncryptionInProgress	The volume is partially encrypted.
DecryptionInProgress	The volume is partially encrypted.
EncryptionPaused	The volume has been paused during the encryption progress. The volume is partially encrypted.
DecryptionPaused	The volume has been paused during the decryption progress. The volume is partially encrypted.

Ohai Version

14 (not a breaking change)

Platform Version

Windows 10, ideally target Windows 2008 upwards (at the very least this should not fail on Windows 2008)
