This change adds support for utilising NVMe specific cleaning tools
on supported devices. This will remove the neccessity of using shred to
securely delete the contents of a NVMe drive and enable using nvme-cli
tools instead, improving cleaning performance and reducing wear on the device.
(this specific change adds extra documentation to the earlier set of
patches implementing this).
