Change the name of the flag to something slightly more user-friendly,
while making it default true. The flag is kept so that someone can
revert it temporarly if things go wrong.
Add a new EmptyResource class that implements openapi.Resources, but
just doesn't have any resources. That is useful for tests that expect
the OpenAPISchema to be working, but don't expect any actual result.
Also implement CreateOpenAPISchemaFunc to simply plug in the TestFactory
code when you want to use an actual APISchema.

ip6tables should be set in the noop plugin
**What this PR does / why we need it**:
The noop plugin currently sets the iptables for IPv4.
This updates that to also set the iptables for IPv6 so
IPv6 can have parity with IPv4.

Enhance label and taint documentation in kubectl
**What this PR does / why we need it**:
This adds some language around how taint and label keys can have a domain + '/' in front of them. From the current documentation, it would seem like these are not allowed even though [well known labels](https://kubernetes.io/docs/reference/labels-annotations-taints/) have them.
Also, it seemed unclear (to me) that both the label's key and value can be 63 characters long. I wanted to clarify this.

**Special notes for your reviewer**:
Phrasing of "_DNS subdomain prefix and '/'_" was copied from [a validator's message](https://github.com/kubernetes/kubernetes/blob/master/staging/src/k8s.io/apimachinery/pkg/util/validation/validation.go#L57) ... I'm unsure if its the best wording, but wanted to be consistent with the validator.

kubectl explain ingress.spec.rules.http.paths. is valid
and defaults to kubectl explain ingress.spec.rules.http.paths
Rational: We use kubectl explain by adding fields
(e.g. service, then service.spec, then service.spec.ports ...)
so it's very easy to forget a trailing . at the end. We should
ignore the trailing period and display the result without it.
