Split informers by internal and external to allow inclusion in client-go
client-go doesn't have any internal clients, so informers which require internal clients can never be included in it. This splits the informer generation into internal and external so we can safely include them.

I tagged it since its straight mechanical.
Added configurable etcd initial-cluster-state to kube-up script. This
allows creation of multi-master cluster from scratch. This is a
cherry-pick of #41320 from 1.5 branch.

resolve udevadm from PATH in cinder_util.go
**What this PR does / why we need it**:
When a cinder volume gets attached to a node, the cinder volume plugin calls `udevadm` with an absolute path `/usr/bin/udevadm`. This path is incorrect for recent versions of debian, ubuntu or the hyperkube image on gcr.io where `udevadm` is located at `/bin/udevadm` or `/sbin/udevadm`. A variant of the hyperkube image is used on CoreOS to run kubelet with rkt fly stage 1.
As a result of the failed `udevadm` exec, the `AttachDisk` function in `cinder_util.go` returns an error.
This PR removes the absolute path from the `udevadm` exec. As a result, `udevadm` is resolved by looking it up in `PATH`.
This is consistent with the gce volume plugin, which executes `udevadm` the same way.

[Federation] Make federation namespace e2e tests parallelizable.
Because deleteAllTestNamespaces deleted all the e2e namespaces it interefered with other federation namespace tests running in parallel. This change should mitigate the problem and make the tests runnable in parallel.

Allow the CertificateController to use any Signer implementation.
**What this PR does / why we need it**:
This will allow developers to create `CertificateController`s with arbitrary `Signer`s, instead of forcing the use of `CFSSLSigner`. It matches the behavior of allowing an arbitrary `AutoApprover` to be passed in the constructor.
**Release note**:
```release-note

Add alternative names for the server binaries to hyperkube
**What this PR does / why we need it**:
Right now one can't swap a server image to the hyperkube image without touching the `command` field in the yaml spec, and that's daunting and leading to extra and unnecessary logic for example in kubeadm.
This makes the hyperkube image directly swappable, so now `/usr/local/bin/kube-*` is a portable first argument (or simply `kube-*` if there's a shell).
**Special notes for your reviewer**:
**Release note**:
```release-note
Align the hyperkube image to support running binaries at /usr/local/bin/ like the other server images
```

Register deepcopy and defaulter funcs for metav1
Houston, we've had a problem here. ObjectMeta had used the reflection fallback path for deepcopy for probably some time.
Remark: my original plan for https://github.com/kubernetes/kubernetes/pull/36412 was/is to rebase that during the master branch freeze for 1.6 and get it merged just before master opens again. Otherwise, I fear it will be rebase hell. With https://github.com/kubernetes/kubernetes/pull/36412 these kind of errors are not possible anymore.
