I'm a long-time proponent of deprecating standalone btrfstune utility,
but so far there's no satisfactory replacement in terms of user
interface.

We've tried to do the uuid rewrite through the properties but it was
kind of blocking the whole feature just because the interface was not
settled.

I'd like to avoid simply adding 'btrfs filesystem tune' with all the
functionality of btrfstune. The thoughts go towards a more generic
command group that could do active opertaions on the filesystem, eg.
similar the 'inspect-internal' to query various stuff.
