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.

Use new fluentd-gcp image version
In #35618 we used new version of fluentd agent, which includes new version of jeamalloc, allowing us to use it.
Additionally, we came up with a hacky way to encourage Ruby GC to be invoked more often by using RUBY_GC_HEAP_OLDOBJECT_LIMIT_FACTOR variable.

Bump glbc version to 0.8.0
Picks up k8s.io godeps for v1.4 thereby fixing an int overflow bug in the upstream delayed-workqueue pkg. Without this the controller spams logs with retries in the "soft error" case, which is easy to come by when users eg: create ingresses that point to non-exist services.
Should go into 1.4.1, because 1.4.0 is pretty much out at this point.

Use etcd 2.3.7
This will switch to etcd 2.3.7 for release 1.4, to resolve issues rolling back from 1.4 to 1.3 (while preventing those same issues rolling back to 1.4.0 from a release including etcd 3.0.x).
Fixes#32253.
See #32253 (comment) for etcd roadmap.
