Replace fmt.Print with proper logging

At some point we should replace all the fmt.Print with https://github.com/sirupsen/logrus or https://github.com/go-logr/logr

Oh, this looks really nice. Add some color, so it's clearer when we're printing errors, or something else.

For the cloud CLI - yes. But not for the server CLI.
