Comment 12 for bug 1835954

Any basic working implementation would be good for start.
Not sure about multiple namespaces - personally I don't think it's needed for first version.

Also, make sure you don't forget there is related bug in linux kernel which gives different device names to namespaces between reboots so /dev/nvme0n1 migth on next reboot be called /dev/nvme1n1

Wish I could add nvme.multipath=0 kernel parameter to maas to use forever but - centos breaks with this parameter.
