add support for nvme devices for tinkerbell provider

[soer3n]

What this PR does / why we need it:
This pr adds support for using nvme disks for tinkerbell provider. For that we need to use the predefined tinkerbell template function formatPartition to respect that such devices have a p as a prefix for the device path. For instance the first partition of a device /dev/nvme0n1 would be /dev/nvme0n1p1.
