[PVE-User] converting privileged CT to unprivileged

[nada at verdnatura.es]

hi Adam,
in general you need these steps at command line (not via webGUI)
1. stop CT
2. backup CT
3. destroy CT
4. restore with special options
5. start CT

example from our mox (version 5.3-9)
root at mox:~# pct restore 120 
/mnt/nas3/vzdump-lxc-120-2019_06_10-16_48_32.tar -ignore-unpack-errors 1 
-unprivileged -force -storage zfs
extracting archive '/mnt/nas3/vzdump-lxc-120-2019_06_10-16_48_32.tar'
tar: ./var/spool/postfix/dev/random: Cannot mknod: Operation not 
permitted
tar: ./var/spool/postfix/dev/urandom: Cannot mknod: Operation not 
permitted
Total bytes read: 893132800 (852MiB, 3.9MiB/s)
tar: Exiting with failure status due to previous errors
Detected container architecture: amd64

do not worry about that errors and start your CT
