You need to know that for now the data is always node dependent,
so currently there's no cluster wide kv-status where one can easily
save things node-independently, or is the SDN status node dependent
anyway?

you can serialize it with encode_json before, and then deserialize
it on reads with decode_json
We explicitly left out internal serialization for now (as the one
reading/writing
keys should be able to know in which format it comes)

no TTL, you can delete it though by just passing the key and leaving
data undef, then it gets deleted for that node.
