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.

Enable caching successful token authentication
Resolves#50472
To support revocation of service account tokens, an etcd lookup of the token and service account is done by the token authenticator. Controllers that make dozens or hundreds of API calls per second (like the endpoints controller) cause this lookup to be done very frequently on the same objects.
This PR:
* Implements a cached token authenticator that conforms to the authenticator.Token interface
* Implements a union token authenticator (same approach as the union request authenticator, conforming to the authenticator.Token interface)
* Cleans up the auth chain construction to group all token authenticators (means we only do bearer and websocket header parsing once)
* Adds a 10-second TTL cache to successful token authentication
```release-note
API server authentication now caches successful bearer token authentication results for a few seconds.

Add UpdateContainerResources method to CRI
This is first step toward support for opinionated cpu pinning for certain guaranteed pods.
In order to do this, the kubelet needs to be able to dynamically update the cpuset at the container level, which is managed by the container runtime. Thus the kubelet needs a method to communicate over the CRI so the runtime can then modify the container cgroup.
This is used in the situation where a core is added or removed from the shared pool to become a exclusive core for a new G pod. The cpuset for all containers in the shared pool will need to be updated to add or remove that core.
Opening this up now so we can start discussion. The need for a change to the CRI might be unexpected.

Manage BUILD files using gazelle + kazel
**What this PR does / why we need it**: uses the upstream `gazelle` tool to manage go rules in BUILD files.

**Special notes for your reviewer**:
It's probably easiest to review this commit-by-commit:
* bump to latest `rules_go` (for recent `cgo_library` and `gazelle` improvements)
* update `kazel` with recent compatibility fixes (https://github.com/kubernetes/repo-infra/pull/28, https://github.com/kubernetes/repo-infra/pull/27), update `hack` scripts to download/build `gazelle`, and then run both `gazelle` and `kazel`. (Additionally make `gazelle` skip things it shouldn't touch.)
* run `hack/update-bazel.sh` to autogenerate everything
* remove the old `cgo_genrule` rules - these are now part of `go_library`
* remove the `automanaged` tags from all go rules - `gazelle` doesn't use them, and it prevents an old version of `kazel/gazel` from messing with the rules
* remove the `licenses()` rules from everywhere but `third_party/` - we don't need them, and `gazelle` won't add them on new `BUILD` files it generates.
