multivalued requirement parser more whitespace tolerant
Query hostIP for instances
Wait/reap build container before removing it

Fixes: https://github.com/GoogleCloudPlatform/kubernetes/issues/1853
Check if cluster is up before e2e test without -up

Minor usability nuisance: If you run:
  go run hack/e2e.go -v -test
.. and you don't happen to have an up e2e cluster, it should fail
fast, rather than chugging through every test and having them fall
over.
