E2E tests for the Source IP Preservation for LoadBalancers
Breaking out E2E changes from the main PR - these tests require the Alpha feature gate turned on for this feature otherwise they will consistently fail.

Get network name via e2e environment.
This should work, right? I plan to pipe it through into the TestContext soon, just not today, and I'd like some test runtime over the weekend. Open to suggestions.

Delete the broken Celery+RabbitMQ example
The celery container used in the example is broken and does not come up
on most distros. The e2e test that was validating this example was not
detecting the fact the celery pod was crash looping.
I attempted to fix the celery container, but it proved to be tedious.
The proposed fix is to update the glibc version to >= 2.23. In this case
it requires updating the python docker image and the celery base image.
https://github.com/kubernetes/kubernetes/issues/31456
has more details.
I'm deleting the example instead of marking it as broken because a user
might overlook the broken warning and it should be trivial to revert
this PR if someone can fix the celery container.

Add ExternalName kube-dns e2e test
ExternalName allows kubedns to return CNAME records for external
services. No proxying is involved.
Built on top of and includes #30599
See original issue at
https://github.com/kubernetes/kubernetes/issues/13748
Feature tracking at
https://github.com/kubernetes/features/issues/33
The e2e test is at least as comprehensive as the one for headless services (namely, only to some degree)
```release-note
Add ExternalName services as CNAME references to external ones
```
Most of the contents of docs/ has moved to kubernetes.github.io.
Development of the docs and accompanying files has continued there, making
the copies in this repo stale. I've removed everything but the .md files
which remain to redirect old links. The .yaml config files in the docs
were used by some tests, these have been moved to test/fixtures/doc-yaml,
and can remain there to be used by tests or other purposes.

Add sysctl support
Implementation of proposal https://github.com/kubernetes/kubernetes/pull/26057, feature https://github.com/kubernetes/features/issues/34
TODO:
- [x] change types.go
- [x] implement docker and rkt support
- [x] add e2e tests
- [x] decide whether we want apiserver validation
- ~~[ ] add documentation~~: api docs exist. Existing PodSecurityContext docs is very light and links back to the api docs anyway: 6684555ed9/docs/user-guide/security-context.md
- [x] change PodSecurityPolicy in types.go
- [x] write admission controller support for PodSecurityPolicy
- [x] write e2e test for PodSecurityPolicy
- [x] make sure we are compatible in the sense of https://github.com/kubernetes/kubernetes/blob/master/docs/devel/api_changes.md
- [x] test e2e with rkt: it only works with kubenet, not with no-op network plugin. The later has no sysctl support.
- ~~[ ] add RunC implementation~~ (~~if that is already in kube,~~ it isn't)
- [x] update whitelist
- [x] switch PSC fields to annotations
- [x] switch PSP fields to annotations
- [x] decide about `--experimental-whitelist-sysctl` flag to be additive or absolute
- [x] decide whether to add a sysctl node whitelist annotation
### Release notes:
```release-note
The pod annotation `security.alpha.kubernetes.io/sysctls` now allows customization of namespaced and well isolated kernel parameters (sysctls), starting with `kernel.shm_rmid_forced`, `net.ipv4.ip_local_port_range`, `net.ipv4.tcp_max_syn_backlog` and `net.ipv4.tcp_syncookies` for Kubernetes 1.4.
The pod annotation `security.alpha.kubernetes.io/unsafeSysctls` allows customization of namespaced sysctls where isolation is unclear. Unsafe sysctls must be enabled at-your-own-risk on the kubelet with the `--experimental-allowed-unsafe-sysctls` flag. Future versions will improve on resource isolation and more sysctls will be considered safe.

**What this PR does / why we need it**:
Currently if there is an error (not found) the error printed out
is to do with the inablity to convert an empty body into the expected json.
This patch will fill in the err correctly.
example of before (with NotFound error):
$ kubectl top node
failed to unmarshall heapster response: json: cannot unmarshal object into Go value of type []v1alpha1.NodeMetrics
Now:
$ kubectl top node
the server could not find the requested resource (get services http:heapster:)

[GarbageCollector] Allow per-resource default garbage collection behavior
What's the bug:
When deleting an RC with `deleteOptions.OrphanDependents==nil`, garbage collector is supposed to treat it as `deleteOptions.OrphanDependents==true", and orphan the pods created by it. But the apiserver is not doing that.
What's in the pr:
Allow each resource to specify the default garbage collection behavior in the registry. For example, RC registry's default GC behavior is Orphan, and Pod registry's default GC behavior is CascadingDeletion.
