Improve documentation for kubeadm preflight command

**What this PR does / why we need it**:
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`

**Which issue(s) this PR fixes**:
part of the effort for [#265](https://github.com/kubernetes/kubeadm/issues/265)

**Special notes for your reviewer**:
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
- `kubeadm-doc-preflight` that implements improvement to `kubeadm alpha phase preflight`

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
```

Parse the last partial line in CRI logs

Signed-off-by: Mrunal Patel <mrunalp@gmail.com>

**What this PR does / why we need it**:
This PR attempts to parse the last line of  log even if it doesn't have a newline. Today for CRI based log formats such lines are ignored and empty output is returned.

kubeadm: Create dnsIP by selecting the tenth IP from k8s svc CIDR

**What this PR does / why we need it**:

Creates dnsIP by selecting the ninth IP from k8s svc cluster IP, instead of appending 0 to the k8s svcIP string.

**Special notes for your reviewer**:
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):
```
