e2e: log wget output on CheckConnectivityToHost error

Log output might help to diagnose e2e flakes, whether they are caused by dns issues or connection timeouts.

Might help with flake https://github.com/kubernetes/kubernetes/issues/28188.

Add a multi-platform proposal

This is a proposal for the work I've done with multiarch Kubernetes. I've worked quite a lot on it and now I've written it down so others may easily use and learn from it, while at the same time pointing out issues that we should fix in the future.

I would like to get this in before `v1.3`.

Feel free to comment on it if it's something that's unclear.

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).

AppArmor was flipped to beta, update feature gate

/cc @dchen1107

---

1.4 Justification:

- Risk: Low. Change is small & contained.
- Rollback: Nothing else should touch this code path or depend on its functionality.
- Cost: AppArmor is beta, but the feature gate thinks it's alpha.

Include security options in the container created event

New container creation events look like:
```
Created container with docker id /k8s_bar2.a4; Security:[seccomp=sub/subtest(md5:07c9bcb4db631f7ca191d6e0bca49f76)]

Created container with docker id /k8s_bar2.a4; Security:[seccomp=unconfined apparmor=foo-profile]
```

The goal is to provide enough information to confirm that the requseted security constraints were honored.

For https://github.com/kubernetes/kubernetes/issues/31284

/cc @dchen1107 @thockin @jfrazelle @pweil- @pmorie

---

Justification for v1.4:

- Risk: low. This appends some additional information to a human readable message. A bug here would probably not break any functionality
- Roll-back: I don't anticipate any more changes to this area of the code. No functionality depends on this change.
- Cost of not including: Users don't get any (positive) confirmation that the AppArmor or Seccomp profile they requested were actually enabled.

test/node-e2e: Update CoreOS update disabling

Previously in this saga... #25004

This disables update-engine and locksmithd with ignition instead of
cloud-init so that they're really totally 100% disabled. Our ignition guy promises.

Pretty much every way of disabling them with cloud-init is mildly racy.

Fixes #31633 

I think @vishh can say "I told you so" after the comment on https://github.com/kubernetes/kubernetes/pull/30023#discussion-diff-73431324 .. he was right, but it turns out "stop" there doesn't really work either because of the mess that is cloud-init. Fortunately, converting our cloud-init to json and calling it "ignition" works quite well 😄 

Testing done: I ssh'd in and verified that yes, they're disabled. I didn't wait on the e2e tests to pass, so we'll let this PR check that.

E2E tests for the Source IP Preservation for LoadBalancers

Breaking out E2E changes from the main PR - these tests require the Alpha feature gate turned on for this feature otherwise they will consistently fail.

This disables update-engine and locksmithd with ignition instead of
cloud-init so that they're really totally 100% disabled.

Pretty much every way of disabling them with cloud-init is mildly racy.

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.

cc @kubernetes/sig-cluster-federation @colhom 

```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.
