Description
@npintaux is seeing long pauses with some deployments of the Cloud Code Go-Guestbook. When running with -v debug, he sees output like:

If you match up the Running commands with the Command outputs, you can see that the final Command output for go-guesbook-frontend at t=0282 corresponds to the kubectl rollout status at t=0101.
Nicolas reports that running kubectl rollout status from the command-line during this pause returns much faster. He's trying to isolate whether this is an issue with the remote cluster or whether it's connection-establishment cost.
Regardless, it would be better if our deployment status checks could talk to the cluster directly over a shared connection rather than repeatedly calling out to kubectl rollout status.
