**What this PR does / why we need it**:
Added missing tests which checks proper handling of `%s` in arguments for command `kubectl apply view-last-applied`
**Which issue this PR fixes**
#54645
**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).
**Which issue this PR fixes**: Fixeskubernetes/kubeadm#498
**Special notes for your reviewer**: Should preferably be cherrypicked to 1.8.
```release-note
Fix `kubeadm upgrade plan` for offline operation: ignore errors when trying to fetch latest versions from dl.k8s.io
