This commit is trying to DRY up the initiation of the gRPC client in
each command:
It renames the function to CLI instead of GRPC as it actually set up a
CLI client, not a generic grpc client
It also moves the configuration of address, timeout (which is now
consistent) and api to use Viper, allowing users to set it via env vars
and configuration file
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.
