Add confirmation prompt for mkosi burn

[nameOfUser0236]

mkosi burn needs a confirmation dialog to avoid nuking a system drive. Additionally it should print out the device size and vendor, and the sizes, file system types, mount points, and names of all partitions. This will add an additional layer of protection. All the required information could be retrieved via this command lsblk -o PATH,LABEL,PARTLABEL,FSTYPE,SIZE,HOTPLUG,MOUNTPOINTS </path/to/device>

I hacked together a quick and dirty implementation for this. link

We should actually fix this by adding an interactive mode to systemd-repart.
