Add node benchmark tests for cos-m60 with docker 1.12.6

Ref: https://github.com/kubernetes/kubernetes/issues/42926

This PR adds a benchmark tests against cos-m60 with docker 1.12.6 on http://node-perf-dash.k8s.io. This test is useful for docker validation -- we can compare the performance of different dockers on the same OS.

cos-m60 comes with docker 1.13.1 by default, so we need to use cloud-init to downgrade the version to 1.12.6.

When not using a CloudProvider, set both InternalIP and ExternalIP on Nodes

#36095 changed all of the cloudproviders to set both InternalIP and ExternalIP on Nodes, but the non-cloudprovider fallback code now only sets InternalIP.

This causes the test "should be able to create a functioning NodePort service" in test/e2e/service.go to fail on cloud-provider-less clusters, because (with LegacyHostIP gone), it now will only try to work with ExternalIPs, and will fail if the node has only an InternalIP.

There isn't much other code that assumes that ExternalIP will always be set (there's something in pkg/master/master.go, but I don't know what it's doing, so maybe it's only useful in the case where InternalIP != ExternalIP anyway). But given that several of the cloudproviders (mesos, ovirt, rackspace) now explicitly set both InternalIP and ExternalIP to the same value always, it seemed right to do that in the fallback case too.

openapi: Add validation logic

This allows validation of a yaml/json object against an openapi schema.
A lot more testing would be needed to validate the logic, and also this
is not plumbed in, so it can't be used by kubectl yet.
