Move 'alpha' KubeletConfiguration fields that aren't feature-gated and self-registration fields to KubeletFlags
Some of these fields are marked "alpha" in help text. They cannot be in the KubeletConfiguration object unless they are feature gated or graduated from alpha.
Others relate to Kubelet self-registration, and given https://github.com/kubernetes/community/pull/911 I think its prudent to wait and see if these really should be in the KubeletConfiguration type.
For now we just leave them all as flags.

This PR is part of the effort for improving kubeadm reference doc (CLI, website, manpages), and more specifically improves documentation for `kubeadm alpha phase preflight`

The PR has two commits:
- `Clone documentation utility from //pkg/kubectl/cmd/templates`, that re-implements in kubeadm some kubectl utilities for handling description and examples for cobra.commands; more PR will follow re-using those utilities. NB. I was forced to add an exception to golint because `blackfriday.Renderer` requires to implement an interface that is not compliant

Adds Octavia v2 as LoadBalancer provider
**What this PR does / why we need it**:
Adds support for using Octavia as the OpenStack LB provider.
**Which issue(s) this PR fixes**:
Although some LB providers can be specified using the [lb-provider](https://github.com/kubernetes/kubernetes/pull/54176/files#diff-694c675fe77b09923cc453e7228f8fa8R85) JSON request field, other installations which use Octavia by default rely on it being discovered via the service catalog. When a user specifies the `load-balancer` service type, it will get back the root Octavia endpoint URL, which needs to have `v2.0` appended to it.
To facilitate this change, gophercloud recently added the `NewLoadBalancerV2` helper in https://github.com/gophercloud/gophercloud/pull/591.
**Release note**:
```release-note
Octavia v2 now supported as a LB provider
```

This is helpful when we have service cluster range CIDR as 10.87.116.64/26 (for example), previously this would have failed while parsing the dnsIP, as we used to append a 0 to the k8s svc clusterIP string. This will get the same dnsIP 10.96.0.10 for very widely used service cluster range CIDR 10.96.0.0/12

add back defaulting for parameter decoding
At the beginning of 1.7, we removed the last "conversion causes defaulting". This broke the "default to true" behavior for exec and attach options, but we didn't notice. This removes the broken defaulter (you can default a non-point bool to true on an object) and adds back defaulting to parameter codecs.

Wait for server resources.
For https://github.com/kubernetes/kubernetes/issues/55768.
In e2e test for containerd, I sometimes see the following fail (e.g. https://k8s-gubernator.appspot.com/build/kubernetes-jenkins/logs/ci-cri-containerd-e2e-gci-gce/178):
```
Nov 15 02:40:31.291: Couldn't delete ns: "e2e-tests-container-probe-dcvlw": unable to retrieve the complete list of server APIs: metrics.k8s.io/v1beta1: the server could not find the requested resource (&discovery.ErrGroupDiscoveryFailed{Groups:map[schema.GroupVersion]error{schema.GroupVersion{Group:"metrics.k8s.io", Version:"v1beta1"}:(*errors.StatusError)(0xc420bfd170)}})
```
Usually, only the first few tests fail with this error. The error seems to be returned at this line https://github.com/kubernetes/kubernetes/blob/master/test/e2e/framework/util.go#L1170.
