**Special notes for your reviewer**:
Added a test case to cover specific issue described.
It fails on version `v1.7.3`..`v1.7.9` and passes since `v1.8.0`.
P.S. Not sure if there is already a lower level test which covers this case in the k8s test suite. I would recommend to add this test, so the issue would not reoccur.

Introduce GCE-specific addons directory
**What this PR does / why we need it**:
GCE & GKE currently rely on the cluster bringup defined in the `cluster/gce` directory, but there isn't a good way of deploying GCE specific manifests. Currently the 2 approaches are, put it in `/cluster/addons`, which implies it should be generally useful (not GCE specific), or it is synthesized by one of the bash scripts in `cluster/gce`.
This PR introduces a straightforward way to have GCE-specific manifests deployed for GCE & GKE, without the need to pollute the general addon space.

Fix `kubeadm upgrade plan` for offline operation
**What this PR does / why we need it**:
This PR allows `kubeadm upgrade plan` to work in firewalled/offline/otherwise restricted environments by ignoring errors when trying to reach dl.k8s.io. Instead, we fall back to the current kubeadm version as the latest stable version. This is a reasonable as a user is [expected to install a recent version of kubeadm before upgrading](https://kubernetes.io/docs/tasks/administer-cluster/kubeadm-upgrade-1-8/#upgrading-your-control-plane).

make iptables wait flag generic and tune it to 5 seconds
Excerpt from [bug](https://bugzilla.redhat.com/show_bug.cgi?id=1506396) opened by @eparis
> iptables-restore has a 2s wait timeout. Data collected today shows that even with a much faster kernel we can reasonably expect iptables-restore to take upwards of 2.4 seconds. (with unpatched/released RHEL kernel this can easily take 7-8 second)
> longest runs I saw over about 30 minutes were:
> 2.267244
> 2.284707
> 2.291535
> 2.376457
> If we get 2 iptables restores going at the same time, with a 2s timeout it is very likely the second will fail.
> I'd like to suggest a 5s timeout. It should still bound the number of thread we may be waiting on and increases the reliability that a common situation will be automatically resolved without failing up the stack.

Add CRI log format support in fluentd.
Without this fluentd will log a lot of errors for each line, because it doesn't recognize the CRI log format.
With this PR, it could support CRI log format now. I've tried with cri-containerd.
The PR is using https://github.com/repeatedly/fluent-plugin-multi-format-parser.
This PR depends on https://github.com/GoogleCloudPlatform/k8s-stackdriver/pull/62.
@crassirostris Should I build/push image before the PR is merged? What is our process?
**Release note**:
```release-note
fluentd now supports CRI log format.

Create kubectl's own instance of Scheme and Registry
Create kubectl's own instance of Registry and Scheme.
Switch most command that doesn't depend on internal types to use kubectl's own scheme and register.
There are some hack of registering the internal types in some of unit test now, they should be gone after switch to the external type.
Switch kubectl's factory code to use kubectl's scheme will create a lot of ripples.
I don't want make this PR a super giant PR, so I will do it in a followup PR.
Partially addressed #48564.
Copy the summary from https://github.com/kubernetes/kubernetes/pull/54533#issuecomment-340522302:
- creates pkg/kubectl/scheme (install.go and scheme.go) with
deps on properly vendored k8s.io packages.
- deletes about 80% percent of dependence on pkg/api/legacyscheme
- replaces direct dependence from pkg/kubectl on
pkg/apis/rbac
to a vendor style dependence on
k8s.io/api/rbac
and removes dependencies on rbac paths containing internalversion
- replaces almost 50% of direct dependence on pkg/api with (properly vendored)
k8s.io/api/core/v1
- deletes all of dependence on pkg/apis/policy and k8s.io/api/policy/v1beta1
