Silent failure on `draft up` with bad registry.token

[frodopwns]

I starting playing with draft today. During the learning process I ran into one event that may be a bug.

Ubuntu 16.10
Helm 2.4.1
Draft Canary (18784fd)

After running draft init and then draft init --set --upgrade to set the config items (I later learned I had set the wrong token for docker.io) I got this output:

~/go/src/github.com/Azure/draft/examples/python on  master! :watch: 17:49:18

The part that I expected but was missing is:

Error encountered streaming JSON response: unauthorized: authentication required

I was unable to recreate this problem.

I have a feeling this will be fixed with the rewrite to grpc in #1. pinging @fibonacci1729 for visibility

[bacongobbler]

closing this as semi-fixed via #154, then finally fixed via the PR incoming to rewrite this via grpc.

@bacongobbler you saw that I had this problem also. SWAG for grpc rewrite? Just curious. @213
