tighten quota controller interface
While debugging a quota performance problem, I had to chase some references deeper than necessary because the interfaces were overly broad. This tightens them.

Static deepcopy – phase 1
This PR is the follow-up of https://github.com/kubernetes/kubernetes/pull/36412, replacing the
dynamic reflection based deepcopy with static DeepCopy+DeepCopyInto methods on API types.
This PR **does not yet** include the code dropping the cloner from the scheme and all the
porting of the calls to scheme.Copy. This will be part of a follow-up "Phase 2" PR.
A couple of the commits will go in first:
- [x] audit: fix deepcopy registration https://github.com/kubernetes/kubernetes/pull/48599
- [x] apimachinery+apiserver: separate test types in their own packages #48601
- [x] client-go: remove TPR example #48604
- [x] apimachinery: remove unneeded GetObjectKind() impls #48608
- [x] sanity check against origin, that OpenShift's types are fine for static deepcopy https://github.com/deads2k/origin/pull/34
TODO **after** review here:
- [x] merge https://github.com/kubernetes/gengo/pull/32 and update vendoring commit

differences between clientset_generated and client-go. The manual changes are isolated into a

kubeadm: change the default bootstrap token TTL to 24 hours
**What this PR does / why we need it**:
This PR changes the TTL for the default bootstrap token generated by `kubeadm init` (without the `--token-ttl` parameter) and `kubeadm token create` (without the `--ttl` flag). Previously, the default TTL was infinite. After this change it is 24 hours.
~~The reasoning for 2 hours as a default is that it's 1) long enough that someone manually using kubeadm (copy-pasting) shouldn't have any issues and 2) short enough that if something is going to break, it should break while the user/admin is still paying attention to the cluster. I'm open to bikeshedding about the exact value, 2 hours is a bit of a strawman.~~
**Edit: updated this to 24 hours instead of 2 hours.**
This is a breaking change if you rely on infinite TTL tokens (e.g., if you had an ASG group of worker nodes). The old behavior is easily restored by passing `--token-ttl 0` to `kubeadm init` or the `--ttl 0` flag to `kubeadm token create`.
**Which issue this PR fixes**: fixes https://github.com/kubernetes/kubeadm/issues/343
**Special notes for your reviewer**:
This was discussed earlier today in SIG-cluster-lifecycle
**Release note**:
```release-note
Change the default kubeadm bootstrap token TTL from infinite to 24 hours. This is a breaking change. If you require the old behavior, use `kubeadm init --token-ttl 0` / `kubeadm token create --ttl 0`.

kubeadm: add a warning about the default token TTL changing in 1.8
**What this PR does / why we need it**:
This adds a warning to `kubeadm init` and `kubeadm token create` if they are run without the `--token-ttl` / `--ttl` flags. In 1.7 and before, the tokens generated by these commands defaulted to an infinite TTL (no expiration) in 1.8, they will generate a token with a 24 hour TTL.
The actual default change is in https://github.com/kubernetes/kubernetes/pull/48783. This change is separate so we can cherry pick the warning into the `release-1.7` branch.
**Which issue this PR fixes**: ref https://github.com/kubernetes/kubeadm/issues/343
**Special notes for your reviewer**:
This change is blocked on https://github.com/kubernetes/kubeadm/issues/343. These warnings should probably be removed in the 1.9 cycle.
**Release note**:
```release-note
Add a runtime warning about the kubeadm default token TTL changes in 1.8.
