TestErrorSpam: retry after the token is automatically created and added to the service account

[tstromberg]

This is two separate errors:

* Restarting the docker service may improve performance

This line of stderr should be whitelisted.

and:

error_spam_test.go:49: unexpected error log in stderr: "Error from server (ServerTimeout): error when creating \"/etc/kubernetes/addons/storage-provisioner.yaml\": No API token found for service account \"storage-provisioner\", retry after the token is automatically created and added to the service account"

This is indicative of a real problem.

This particular flake seems fairly rare.
