There is a concern that some GCE users may be running automation that
(a) turns up ephemeral clusters and (b) always uses the latest K8s
release. If any of these workloads fall outside the set supported on
GCI, cutting the release will break the automation. We are therefore
delaying this change until we have provided sufficient warning.

Migrates addons from RCs to Deployments
Fixes#33698.
Below addons are being migrated:
- kube-dns
- GLBC default backend
- Dashboard UI
- Kibana
For the new deployments, the version suffixes are removed from their names. Version related labels are also removed because they are confusing and not needed any more with regard to how Deployment and the new Addon Manager works.
The `replica` field in `kube-dns` Deployment manifest is removed for the incoming DNS horizontal autoscaling feature #33239.
The `replica` field in `Dashboard` Deployment manifest is also removed because the rescheduler e2e test is manually scaling it.
Some resource limit related fields in `heapster-controller.yaml` are removed, as they will be set up by the `addon resizer` containers. Detailed reasons in #34513.
Three e2e tests are modified:
- `rescheduler.go`: Changed to resize Dashboard UI Deployment instead of ReplicationController.
- `addon_update.go`: Some namespace related changes in order to make it compatible with the new Addon Manager.
- `dns_autoscaling.go`: Changed to examine kube-dns Deployment instead of ReplicationController.
Both of above two tests passed on my own cluster. The upgrade process --- from old Addons with RCs to new Addons with Deployments --- was also tested and worked as expected.
The last commit upgrades Addon Manager to v6.0. It is still a work in process and currently waiting for #35220 to be finished. (The Addon Manager image in used comes from a non-official registry but it mostly works except some corner cases.)
@piosz @gmarek could you please review the heapster part and the rescheduler test?

Notes:
- Kube-dns manifest still uses *-rc.yaml for the new Deployment. The stale file names are preserved here for receiving faster review. May send out PR to re-organize kube-dns's file names after this.
- Heapster Deployment's name remains in the old fashion(with `-v1.2.0` suffix) for avoiding describe this upgrade transition explicitly. In this way we don't need to attach fake apply labels to the old Deployments.

Print osImage and kubeletVersion for nodes before and after GCE upgrade
This will print, e.g.:
```
== Pre-Upgrade Node OS and Kubelet Versions ==
name: "e2e-test-mtaufen-master", osImage: "Google Container-VM Image", kubeletVersion: "v1.4.5-beta.0.45+90d209221ec8dc-dirty"
name: "e2e-test-mtaufen-minion-group-jo79", osImage: "Debian GNU/Linux 7 (wheezy)", kubeletVersion: "v1.4.5-beta.0.45+90d209221ec8dc-dirty"
name: "e2e-test-mtaufen-minion-group-ox5l", osImage: "Debian GNU/Linux 7 (wheezy)", kubeletVersion: "v1.4.5-beta.0.45+90d209221ec8dc-dirty"
name: "e2e-test-mtaufen-minion-group-qvbq", osImage: "Debian GNU/Linux 7 (wheezy)", kubeletVersion: "v1.4.5-beta.0.45+90d209221ec8dc-dirty"
```
Let me know what output format you prefer and I'll see if I can make it work, I have the extent of flexibility allowed by jsonpath.

It seems like the `kubectl` behavior was introduced in #29236: if `current-context` is set to something invalid, it now complains.

[Kubelet] Use the custom mounter script for Nfs and Glusterfs only
This patch reduces the scope for the containerized mounter to NFS and GlusterFS on GCE + GCI clusters
This patch also enabled the containerized mounter on GCI nodes
Shepherding multiple PRs through the submit queue is painful. Hence I combined them into this PR. Please review each commit individually.

e2e node plumbing and bundling for GCI mounter
**Note:** The code in this PR only bundles the mounter and modifies `--mounter-path` if it can find `cluster/gce/gci/mounter` in the K8s source dir when building the test bundle.
This bundles the mounter script for GCI with the node e2e tests and allows the `--mounter-path` to be passed to the Kubelet via the node test framework. The node test runner will detect when we are running on a remote GCI node and add the appropriate `--mounter-path` to the `testArgs`.
It also includes a simple node test that mounts a tmpfs volume. This will exercise the Kubelet's mounter code path.
**ITEM OF NOTE:** To get the k8s root dir (in order to copy the mount script into the tarball), I changed `getK8sRootDir` -> `GetK8sRootDir` in `test/e2e_node/build/build.go`. Based on the comment above that function (and the fact that it was private to begin with), I'm not sure this is the best way to do things:
```
// TODO: Dedup / merge this with comparable utilities in e2e/util.go
```
On the other hand, the `e2e/util.go` file mentioned in that comment doesn't exist anymore. This should be resolved before this PR is merged.

Add gcl cluster logging test
This PR changes default logging destination for tests to gcp and adds test for cluster logging using google cloud logging
Fix#20760
The original fix (#33147) sourced the correct `node-helper.sh` but set
`node_os_distribution` instead of `NODE_OS_DISTRIBUTION`. The
`set-node-image` function is imported indirectly via `source
"${KUBE_ROOT}/cluster/kube-util.sh"`, which in turn (in the GCE case)
sources `cluster/gce/util.sh`. Since the `set-node-image` function
relies on the `NODE_OS_DISTRIBUTION` variable, the original fix
did not have the entire intended effect.
I have confirmed that cherry-picking #33147 into the `release-1.4`
branch and layering this commit on top of it make for a successful
upgrade from a GCI based K8s 1.3 cluster to a GCI based K8s 1.4 cluster.
