I would rather keep the json functionality separate from this.
Yes, I know that we really need json functionality to make it usable, 
but then the same could be said for other options, too.

And the problem here is that we'll need to coordinate libnvme and 
nvme-cli updates to get the whole thing to build, so I'd rather keep the 
json update separate from this one.

Cheers,

Hannes
