Rewrite staging import verifier in Go

**What this PR does / why we need it**:
Maintaining Bash is nobody's idea of fun. The declarative config is infinitely easier to read, as well.
**Special notes for your reviewer**:
@sttts still trying to figure out the rules you have encoded in the shell script... very confusing. Please review the `kube-gen` specifically.

Simplify hack/verify-flags-underscore.py
**What this PR does / why we need it**:
This PR removes the need for `hack/verify-flags/known-flags.txt` and verify-flags-underscore.py will always parse the flags from go files to check if they have underscore.
It is much faster compared to earlier checks and it does its job to check for underscore in flags.
Now:
```
# time ./hack/verify-flags-underscore.py
real 0m1.638s
user 0m1.560s
sys 0m0.076s
```
Before:
```
# time ./hack/verify-flags-underscore.py
real 0m22.585s
user 0m22.464s
sys 0m0.112s
```
It has become a pain to keep adding new flag to `known-flags.txt` whenever a new flag is introduced. with this PR this is step is not required anymore.

kubeadm: Move all node bootstrap token related code in one phase package
**What this PR does / why we need it**:
Part of the phases refactoring.
Moves everything Node Bootstrap Token-related into its own package.
In the future there will be a `phases/bootstraptoken/master` pkg as well.
The generic bootstrap token client functions should be moved to client go eventually https://github.com/kubernetes/client-go/issues/114

Target godep script change verifications
helps with #50319
`hack/verify-godeps.sh` takes ~15 minutes of the verify job time. We should not run it if not required, especially since the job is regularly timing out at 1 hour when this check is included.
https://github.com/kubernetes/kubernetes/pull/48653 added a check to run it if *anything* under `hack` was changed. This targetes just changes to the godep scripts

Alpha Dynamic Kubelet Configuration
Feature: https://github.com/kubernetes/features/issues/281
This proposal contains the alpha implementation of the Dynamic Kubelet Configuration feature proposed in ~#29459~ [community/contributors/design-proposals/dynamic-kubelet-configuration.md](https://github.com/kubernetes/community/blob/master/contributors/design-proposals/dynamic-kubelet-configuration.md).
Please note:
- ~The proposal doc is not yet up to date with this implementation, there are some subtle differences and some more significant ones. I will update the proposal doc to match by tomorrow afternoon.~
- ~This obviously needs more tests. I plan to write several O(soon). Since it's alpha and feature-gated, I'm decoupling this review from the review of the tests.~ I've beefed up the unit tests, though there is still plenty of testing to be done.
- ~I'm temporarily holding off on updating the generated docs, api specs, etc, for the sake of my reviewers 😄~ these files now live in a separate commit; the first commit is the one to review.
/cc @dchen1107 @vishh @bgrant0607 @thockin @derekwaynecarr
```release-note
Adds (alpha feature) the ability to dynamically configure Kubelets by enabling the DynamicKubeletConfig feature gate, posting a ConfigMap to the API server, and setting the spec.configSource field on Node objects. See the proposal at https://github.com/kubernetes/community/blob/master/contributors/design-proposals/dynamic-kubelet-configuration.md for details.

[Federation] Make the hpa scale time window configurable
This PR is on top of open pr https://github.com/kubernetes/kubernetes/pull/45993.
Please review only the last commit in this PR.
This adds a config param to controller manager, the value of which gets passed to hpa adapter via sync controller.
This is needed to reduce the overall time limit of the hpa scaling window to much lesser (then the default 2 mins) to get e2e tests run faster. Please see the comment on the newly added parameter.
**Special notes for your reviewer**:
@kubernetes/sig-federation-pr-reviews
@quinton-hoole
@marun to please validate the mechanism used to pass a parameter from cmd line to adapter.
**Release note**:
```
federation-controller-manager gets a new flag --hpa-scale-forbidden-window.
This flag is used to configure the duration used by federation hpa controller to determine if it can move max and/or min replicas
around (or not), of a cluster local hpa object, by comparing current time with the last scaled time of that cluster local hpa.
Lower value will result in faster response to scalibility conditions achieved by cluster local hpas on local replicas, but too low
a value can result in thrashing. Higher values will result in slower response to scalibility conditions on local replicas.

Fix sort-by output problem
Fixes https://github.com/kubernetes/kubectl/issues/43
This bug was original introduced in pr here: https://github.com/kubernetes/kubernetes/pull/46265, I think next time if we touch something printer related package, maybe should let @smarterclayton have a review, although he is pretty busy I guess : ) and that package also changed a lot recently since he's been working on refactoring.
this is a quick and dirty fix, not sure if there's better way, I will add some regression test soon...

Add a simple cloud provider for e2e tests on kubemark
**What this PR does / why we need it**:
Adds a simplified cloud provider for kubemark. This enables us to add and
remove nodes and operate on nodegroups while running tests on kubemark.
This is needed to run scalability tests for cluster autoscaler on kubemark.

convert default predicates to use the default
Builds on https://github.com/kubernetes/kubernetes/pull/50019 (lgtm'd already)
This converts the already default field selectors to use the default value. I'll let CI point out the unit test failures for me to chase.
@kubernetes/sig-api-machinery-misc
This is needed for cluster autoscaler e2e test to
run on kubemark. We need the ability to add and
remove nodes and operate on nodegroups. Kubemark
does not provide this at the moment.

```release-note
Kubelet will by default fail with swap enabled from now on. The experimental flag "--experimental-fail-swap-on" has been deprecated, please set the new "--fail-swap-on" flag to false if you wish to run with /proc/swaps on.

Reintegrate aggregation support for OpenAPI
Reintegrating changes of #46734
Changes summary:
- Extracted all OpenAPI specs to new repo `kube-openapi`
- Make OpenAPI spec aggregator to copy and rename any non-requal model (even with documentation change only).
- Load specs when adding APIServices and retry on failure until successful spec retrieval or a 404.
- Assumes all Specs except aggregator's Spec are static
- A re-register of any APIService will result in updating the spec for that service (Suggestion for TPR: they should be registered to aggregator API Server, Open for discussion if any more changes needed for another PR.)
