kubeadm: Use separate YAML docs for the kubelet and kube-proxy ComponentConfigs

**What this PR does / why we need it**:
This PR makes kubeadm load the ComponentConfig for the kubelet and kube-proxy from separate YAML documents in the `kubeadm init` config file. This is backwards-compatible with `v1alpha2`. The ComponentConfigs are stored internally in the internal kubeadm `MasterConfiguration` struct, but when marshalling the componentconfigs are written as separate YAML documents.

kubeadm: Start using internal versions for ComponentConfigs in the internal API

**What this PR does / why we need it**:
This PR changes kubeadm to store the internal API versions of the ComponentConfig APIs, in order to in the future be able to read multiple external versions with conversion. It also moves all the ComponentConfigs to a common struct instead of splitting them out in many. This makes it possible to more easily host more ComponentConfigs in the future. In v1alpha3, the ComponentConfigs will later be removed from the external version of the API (see: https://github.com/kubernetes/kubernetes/pull/65787), but for this PR no changes to the external API are made.

Adding details to Conformance Tests using RFC 2119 standards.

This PR is part of the conformance documentation. This is to provide more formal specification using RFC 2119 keywords to describe the test so that who ever is running conformance tests do not have to go through the code to understand why and what is tested.
The documentation information added here into each of the tests eventually result into a document which is currently checked in at location https://github.com/cncf/k8s-conformance/blob/master/docs/KubeConformance-1.9.md

I would like to have this PR reviewed for v1.10 as I consider it important to strengthen the conformance documents.

Avoid printing some service comments in iptables rules

According to some profiles, with large number of endpoints in the system, comments mentioning the service in appropriate iptables rules may be responsible for 40% of all iptables contents.

Given that ~70% of memory usage of kube-proxy seems to be because of generated iptables rules, the overall saving may be at the level of 30% or so.

OTOH, we sacrifise a bit understandability of iptables, but this PR only changes some of iptables that contribute to the most painful rules.

@thockin @danwinship @dcbw - thoughts?

Add script to verify generated files

**What this PR does / why we need it**:
This is probably *really* heavy handed fix to this, but it will catch issues in presubmit.

Basically, takes a copy of the repo, clears out anything that is ignored from the git tree, runs `make generated_files`, and looks for a git diff. If there is one, error. Anything that is properly gitignored won't cause a diff, but anything that is *supposed* to be checked in, but is different, this will catch.

**Special notes for your reviewer**:
I'm open to more elegant answers, but this will at least stop it from happening for now.
