roachtest: cluster_creation failed

**Note:** This build has runtime assertions enabled. If the same failure was hit in a run without assertions enabled, there should be a similar failure without this message. If there isn't one, then this failure is likely due to an assertion violation or (assertion) timeout.

Start with the linked TeamCity build and artifacts, then read pkg/cmd/roachtest/README.md and the cluster_creation test entry point. The report shows a Google Compute Engine stockout in us-central1-b; it does not specify a code change or acceptance criteria, so done cannot be determined from the issue alone.
