Deploy a default StorageClass instance on AWS and GCE
This needs a newer kubectl in kube-addons-manager container. It's quite tricky to test as I cannot push new container image to gcr.io and I must copy the newer container manually.

**Release note**:
```release-note
Kubernetes now installs a default StorageClass object when deployed on AWS, GCE and
OpenStack with kube-up.sh scripts. This StorageClass will automatically provision
a PeristentVolume in corresponding cloud for a PersistentVolumeClaim that cannot be
satisfied by any existing matching PersistentVolume in Kubernetes.
To override this default provisioning, administrators must manually delete this default StorageClass.

Modify GCI mounter to enable NFSv3
In order to make NFSv3 work, mounter needs to start rpcbind daemon. This
change modify mounter's Dockerfile and mounter script to start the
rpcbind daemon if it is not running on the host.
After this change, need to make push the image and update the sha number in Changelog.

Eviction Thresholds Update
Sets the defaults for the eviction-hard threshold for GCE based on what we were using during testing: "memory.available<250Mi,nodefs.available<10%,nodefs.inodesFree<5%".
Sets flags for e2e tests to use eviction-minimum-reclaim: "nodefs.available<5%,nodefs.inodesFree<5%"
this fixes#32537
- Adds command line flags --config-map, --config-map-ns.
- Fixes 36194 (https://github.com/kubernetes/kubernetes/issues/36194)
- Update kube-dns yamls
- Update bazel (hack/update-bazel.sh)
- Update known command line flags
- Temporarily reference new kube-dns image (this will be fixed with
a separate commit when the DNS image is created)
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.

In effect, in HA mode in case of multiple masters, IP of external load

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.
