convert TPR controller to posthook instead of disable flag
Converts the third party resource controller into a posthook using a loopback client instead going direct to etcd. This let's us eliminate more flags and special-casing during initialization. Also, using a client brings us closer to building this without side-effects for downstream composers.

glog non-fatal, usually unimportant error instead of fmt
Fixes https://github.com/kubernetes/kubernetes/issues/34977
This particular message isn't usually important, so demote it to glog.

make version an explicit choice so zero config and customized work
Makes `/version` key off of setting the version. This allows composers to add a version that is correct.

New client-go structure
This PR is part of restructuring client-go (https://github.com/kubernetes/client-go/issues/9#issue-181545998). In short, the top-level folder for client-go versions are removed.
This PR also runs copy.sh to pick up changes in the main repository. The number of files in client-go has increase from 1361 files to 1405.

Don't store Gluster SotrageClass parameters in annotations, it's insecure.
Instead, expect that there is the StorageClass available at the time
when it's needed by Gluster deleter.

Improvements to CLI usability and maintainability
Improves `kubectl` from an usability perspective by
1. Fixing how we handle terminal width in help. Some sections like the flags use the entire available width, while others like long descriptions breaks lines but don't follow a well established max width (screenshot below). This PR adds a new responsive writer that will adjust to terminal width and set 80, 100, or 120 columns as the max width, but not more than that given POSIX best practices and recommendations for better readability.
2. Adds our own normalizers for long descriptions and cmd examples which allows us better control about how things like lists, paragraphs, line breaks, etc are printed. Features markdown support. Looks like `templates.LongDesc` and `templates.Examples` instead of `dedent.Dedend`.
3. Allows simple reordering and reuse of help and usage sections.
3. Adds `verify-cli-conventions.sh` which intends to run tests to make sure cmd developers are using what we propose as [kubectl conventions](https://github.com/kubernetes/kubernetes/blob/master/docs/devel/kubectl-conventions.md). Just a couple simple tests for now but the framework is there and it's easy to extend.
4. Update [kubectl conventions](https://github.com/kubernetes/kubernetes/blob/master/docs/devel/kubectl-conventions.md) to use our own normalizers instead of `dedent.Dedent`.

Do not cache hyperkube package installation
**What this PR does / why we need it**:
The hyperkube build process could use a cached layer containing out of date packages. For example, the v1.4.0 image contains packages with security vulnerabilities, which should have been available as of the release build date.
This was surfaced from quay.io/clair scanning the hyperkube images:

Escape special characters in jsonpath field names.
There may be a better way to do this, but this seemed like the simplest possible version.

Add test_list command, to enumerate unit and e2e tests.
This uses go/parser and go/ast to analyze all test files in ~1 second.
It only recognizes a few simple structures that the tests all have, and
modifies a few tests to fit expected structure better.
This is part of an effort to ensure all tests have owners, by having a
verify check to catch new tests being added without an owner.
