cli: down works on gyaml

[jazzdan]

From Kubernetes slack:

Quick question: should tilt down delete all resources created from k8s_yaml? I’m not seeing an easy way to clean up configmaps etc created by tilt up.

I’m seeing this with any resource that doesn’t reference an image that tilt knows about… so if my Tiltfile just contains

k8s_yaml("pod.yaml")

tilt up creates the pod, but it remains after tilt down

We simply weren't also deleting the global YAML resources that we record in the Tiltfile when down is called.

While I was here I made a change to the k8s client to print out which resources we're deleting, similarly to how we do it in Upset. Looks like this:

[~/go/src/github.com/windmilleng/servantes]> tilt down

I didn't write a test because it seemed hard to test and isn't testing a whole lot of logic. Open to ideas though!

LGTM

why did you remove this? this is pretty important

[jazzdan]

Yeah I realized that and added it back.

This will crash if the string contains any % signs.

You should either use Infof inside the loop (rather than have a separate Printf) or use something like Infof("%s", string)
