Add flag to set CNI bin dir, and use it on gci nodes
**What this PR does / why we need it**:
When using `kube-up` on GCE, following #31023 which moved the workers from debian to gci, CNI just isn't working. The root cause is basically as discussed in #28563: one flag (`--network-plugin-dir`) means two different things, and the `configure-helper` script uses it for the wrong purpose.
This PR adds a new flag `--cni-bin-dir`, then uses it to configure CNI as desired.
As discussed at #28563, I have also added a flag `--cni-conf-dir` so users can be explicit
**Which issue this PR fixes** : fixes#28563
**Special notes for your reviewer**:
I left the old flag largely alone for backwards-compatibility, with the exception that I stop setting the default when CNI is in use. The value of `"/usr/libexec/kubernetes/kubelet-plugins/net/exec/"` is unlikely to be what is wanted there.
**Release note**:
```release-note
Added new kubelet flags `--cni-bin-dir` and `--cni-conf-dir` to specify where CNI files are located.
Fixed CNI configuration on GCI platform when using CNI.

Node E2E: Move the image and host related logic to be remote run specific.
This PR addresses #31597, and better fixes#31588.
With this PR:
1) All remote logic is moved into remote mode.
2) All gci related logic is only called when `HOSTS` and `IMAGES` are not specified.
3) Run node e2e against other node e2e images will work again - `make test-e2e-node REMOET=true IMAGES=e2e-node-containervm-v20160321-image`.
4) List images will work again - `make test-e2e-node REMOTE=true LIST_IMAGES=true`.
Mark 1.4, because https://github.com/kubernetes/kubernetes/pull/31588 is marked as 1.4. And this makes the node e2e work as is described in the [doc ](https://github.com/kubernetes/kubernetes/blob/master/docs/devel/e2e-node-tests.md#run-tests-using-different-images).

Separate federation build.sh into development and deployment scripts.
The idea behind this separation is that it provides a clear distinction
between the dev environment and the prod environment. The
deploy/deploy.sh script will be shipped to the users, but
develop/develop.sh will be purely for development purposes and won't
be part of a release distribution.
Purely for developer convenience, all the deployment functionality is
made available through the develop/develop.sh script.
This change also copies deploy/* files into the release distribution.

```release-note
Federation can now be deployed using the `federation/deploy/deploy.sh` script. This script does not depend on any of the development environment shell library/scripts. This is an alternative to the current `federation-up.sh`/`federation-down.sh` scripts. Both the scripts are going to co-exist in this release, but the `federation-up.sh`/`federation-down.sh` scripts might be removed in a future release in favor of `federation/deploy/deploy.sh` script.

Node Conformance Test: Refactor node e2e framework
For #30122, #30174.
Based on #30348.
**Please only review the last 3 commits.**
This PR is part of our roadmap to package node conformance test.
The 1st commit is from #30348, it removed unnecessary dependencies in the node e2e test framework, because we've statically linked these dependencies.
The PR refactored the node e2e framework. Moving different utilities into different packages under `pkg/`.
We need to do this because:
1) Files like e2e_remote.go and e2e_build.go should only be used by runner, but they were compiled into the test suite because they were placed in the same package. The worst thing is that it will introduce some never used flags in the test suite binary.
2) Make the directory structure more clear. Only test should be placed in `test/e2e_node`, other utilities should be placed in different packages in `pkg/`.

Add kubelet --network-plugin-mtu flag for MTU selection
* Add network-plugin-mtu option which lets us pass down a MTU to a network provider (currently processed by kubenet)
* Add a test, and thus make sysctl testable
MTU selection is difficult, and if there is a transport such as IPSEC in
use may be impossible. So we allow specification of the MTU with the
network-plugin-mtu flag, and we pass this down into the network
provider.
Currently implemented by kubenet.

Kubelet: add --container-runtime-endpoint and --image-service-endpoint
Flag `--container-runtime-endpoint` (overrides `--container-runtime`) is introduced to identify the unix socket file of the remote runtime service. And flag `--image-service-endpoint` is introduced to identify the unix socket file of the image service.
This PR is part of #28789 Milestone 0.

Continue on the older PR https://github.com/kubernetes/kubernetes/pull/30094 as there are too many comments on that one and it's not loadable now.
New flag --container-runtime-endpoint (overrides --container-runtime)
is introduced to kubelet which identifies the unix socket file of
the remote runtime service. And new flag --image-service-endpoint is
introduced to kubelet which identifies the unix socket file of the

A build and deploy script to manage cluster federation lifecycle and a Makefile wrapper to drive that process.
Also includes a sample config file to describe clusters.
The build script implements the following things:
1. Generates the required configs.
2. Builds the hyperkube binary and the corresponding docker image.
3. Pushes the image to a specified repository.
4. Pulls the federation installer docker images.
5. Builds the Kubernetes clusters described the config.json file.
6. Pushes the federation components to one of the Kubernetes clusters
built in the previous step.
7. Also turns down the federation components and the Kubernetes
clusters.
**NOTE**: Installer images are right now being pulled from my public repository of docker images. I am working on pushing them to our release repository.
```release-note
Cluster Federation components can now be built and deployed using the make command. Please see federation/README.md for details.

[Kubelet] Rename `--config` to `--pod-manifest-path`. `--config` is deprecated.
This field holds the location of a manifest file or directory of manifest
files for pods the Kubelet is supposed to run. The name of the field
should reflect that purpose. I didn't change the flag name because that
API should remain stable.
