Kristoffer Dalby 79871d2463 Make namespace command use gRPC
This commit is a first in a series of commits migrating the command
interfaces to use the new gRPC client.

As a part of this commit, they have been streamlined and each command
_should_ be a bit more similar and use consistent output.

By using the new output function, we now make sure its always json
(errors and everything) if the user asks for JSON.
