Switch pv controller to shared informer
This is WIP because I still need to do something with bazel? and add 'get storageclasses' to the controller-manager rbac role
@jsafrane PTAL and make sure I did not break anything in the PV controller. Do we need to clone the volumes/claims we get from the shared informer before we use them? I could not find a place where we modify them but you would know for certain.
cc @ncdc because I copied what you did in your other PRs.

Reduce default value of kubemark's NUM_NODES to 10
Changing the default value of kubemark's NUM_NODES from 100 to 10, as it would then be possible to start kubemark on gce clusters that have been started using kube-up that uses the default config of three n1-standard-2 nodes. I've already been asked by a couple of people about why kubemark is not starting on their cluster because of this. More people shouldn't be facing this issue in future.

Add cluster logging load test for GCL
Changed code around logging tests a little to avoid duplication. Added GCL go library, because command line tool cannot handle required number of logs effectively.

Modify kubemark run-e2e-tests.sh to run right command based on environment
In order to run-e2e-tests.sh in kubemark, we currently need to toggle comment b/w the last 2 lines of the script. This is inconvenient to change each time and sometimes this change gets accidentally included as part of a PR. It's even difficult for someone newly trying kubemark to figure this out in order to run tests. Changed the logic to use the right command based on whether the script is running from within a docker container or just locally.

dockertools: call TearDownPod when GC-ing infra pods
The docker runtime doesn't tear down networking when GC-ing pods.
rkt already does so make docker do it too. To ensure this happens,
infra pods are now always GC-ed rather than gating them by
containersToKeep.
This prevents IPAM from leaking when the pod gets killed for
some reason outside kubelet (like docker restart) or when pods
are killed while kubelet isn't running.

kubeadm: Reorder the token packages more logically
**What this PR does / why we need it**:
In order to be able to implement https://github.com/kubernetes/kubernetes/pull/41417, the token functionality (which now is spread across the codebase), should be in two places: a generic token functions library, which in the future _may_ [move into client-go](https://github.com/kubernetes/kubernetes/pull/41281#discussion_r101357106) in some form, and a package for the token handling against the api server.
This commit has no large functional changes.
```
kubeadm: Aggregate the token functionality in sane packages.
- Factor out token constants to kubeadmconstants.
- Move cmd/kubeadm/app/util/{,token/}tokens.go
- Use the token-id, token-secret, etc constants provided by the bootstrapapi package
- Move cmd/kubeadm/app/master/tokens.go to cmd/kubeadm/app/phases/token/csv.go
This refactor basically makes it possible to hook up kubeadm to the BootstrapSigner controller later on

[hairpin] fix argument of nsenter
**Release note**:
```release-note
None
```
We should use:
nsenter --net=netnsPath -- -F some_command
instend of:
nsenter -n netnsPath -- -F some_command
Because "nsenter -n netnsPath" get an error output:
# nsenter -n /proc/67197/ns/net ip addr
nsenter: neither filename nor target pid supplied for ns/net
If we really want use -n, we need to use -n in such format:
# sudo nsenter -n/proc/67197/ns/net ip addr

Proxy defer on update events
This PR is a series of discrete movements in refactoring some of kube-proxy's twistier code in prep to be more async. It should be reviewed one commit at a time. Each commit is a smallish movement, which should be easier to examine. I added significant tests along the way, which, unsurprisingly, found some bugs.

several issues hit while trying to make it easy to register APIs
I was trying to create a script that would register all API versions on a given server and ended up hitting several problems. These are the fixes.
@sttts I suspect that I won't be able to continue down the host-network approach, since that means I won't be able to use in-cluster DNS without some finagling. It *could* be set up (and we make it work as a for instance), but the simple enablement approach will be hosted on the infrastructure. I'll go back to that.

add front proxy to kubeadm created kube-apiservers
The front proxy authenticator configuration has been in a release or two. It allows a front proxy (secured by mutual TLS auth) to provide user information for a request. The kube-aggregator uses this to securely terminate authentication (has to terminate TLS and thus client-certs) and communicate user info to backing API servers.
Since the kube-apiserver always verifies the front-proxy via a client certificate, this isn't open for abuse unless you already have access to either the signing key or client cert which kubeadm creates locally. If you got there, you already owned the box. Therefore, this adds the authenticator unconditionally.

Dead infra containers may still have network resources allocated to
them and may not be GC-ed for a long time. But allowing SyncPod()
to restart an infra container before the old one is destroyed
prevents network plugins from carrying the old network details
(eg IPAM) over to the new infra container.
The docker runtime doesn't tear down networking when GC-ing pods.
rkt already does so make docker do it too. To ensure this happens,
networking is always torn down for the container even if the
container itself is not deleted.
This prevents IPAM from leaking when the pod gets killed for
some reason outside kubelet (like docker restart) or when pods
are killed while kubelet isn't running.

We need to tear down networking when garbage collecting containers too,
and GC is run from a different goroutine in kubelet. We don't want
container network operations running for the same pod concurrently.
