Until we have a better solution in place this enables us to bootstrap the build cache. Basically when starting with a completely empty cache the build will stop halfway, which will partially populate the cache and make the next build go faster. The majority of this change is to ensure that "halfway" captures enough things to make for a substantial initial cache. The algorithm to decide if the cache is "cold" is kind of naive, we really test for "the cache has 0 bytes". Obviously this will not work sometimes, for example, if the cache is full of garbage. In that case we can manually clear the cache in Travis and start over. I created googleapis#1800 to track a real solution, because these hacks are not awesome.
