Hey @wolf4ood @Gsantomaggio what do you think? This is the first step of the superstream implementation. If fine I will continue with the Partitions and Routes commands

[DanielePalaia]

@wolf4ood @Gsantomaggio We can also close this one and review directly #230 containing also ROUTE and PARTITIONS commands with some refactoring on tests

Superseded by #230
