TBR

Reverting. Two issues:
- broke a vm standalone test
- I excluded some DEPS that I should have kept

(I had added a few new DEPS before trying this idea, when I tried this idea I
reverted the changes in the DEPS, but I didn't delete my third_party/pkg/
folder, so I had some stale data and tests passed locally).
