Update Dashboard addon to version 1.8.0 and align /ui redirect with it
**What this PR does / why we need it**: In Dashboard 1.8.0 we have introduced a couple of changes (security, settings, new resources etc.) and fixed a lot of bugs. You can check release notes at https://github.com/kubernetes/dashboard/releases/tag/v1.8.0.

**Special notes for your reviewer**:
**Release note**:
```release-note
Updated Dashboard add-on to version 1.8.0.
- The Dashboard add-on now deploys with https enabled
- The Dashboard can be accessed via kubectl proxy at http://localhost:8001/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/
- The /ui redirect is deprecated and will be removed in 1.10
```
fluend-gcp already has these tolerations. kube-proxy when it runs as a
static pod gets wildcard `NoExecute` toleration (all static pods get
that). So, added the same toleration to kube-proxy when it runs as a
daemonset. Also added wildcard `NoSchedule` toleration to kube-proxy.
It is expected that nodes with extended resources attached will be
tainted with the resouce name, so that we can create dedicated nodes.
If ExtendedResourceToleration admission controller is enabled, pods
requesting such resources will automatically tolerate such taints.
nvidia-gpu-device-plugin daemonset doesn't request such resources but
still needs to run on such nodes, so it needs this toleration.

Changes nvidia-gpu device plugin addon config settings:
- Runs as system critical pod
- Makes resource limits to match its resource requets
- Modifies test/e2e/scheduling/nvidia-gpus.go to cope with the recent
change of running the device plugin as a system addon.
- The resource settings of the addon is based on the test results
from 8 nvidia-tesla-k80 gpus.

Add partial CRI container log support.
For https://github.com/kubernetes/kubernetes/issues/44976.
New CRI log format:
```
TIMESTAMP STREAM TAG CONTENT
2016-10-06T00:17:09.669794202Z stdout P log content 1
2016-10-06T00:17:09.669794203Z stdout P log content 2
```
Although unlikely, if in the future we need more metadata in each line, we could extend TAG into multiple tags splitted by `:`.

Fix prometheus-to-sd sidecar in metadata proxy
Ref https://github.com/kubernetes/kubernetes/issues/55695#issuecomment-344300188
This is making 2 changes:
- restoring resource requests and limits of the metadata-proxy sidecar as it was before, and remove them for prom-to-sd sidecar (best effort) like at everywhere else
- pass pod name and namespace args to prom-to-sd sidecar (because just noticed)

Use results of kube-controller-manager leader election in addon manager
**What this PR does / why we need it**:
This adds leader election-like mechanism to addon manager. Currently, in a multi-master setup, upgrading one master will trigger a fight between addon managers on different masters, each forcing its own versions of addons. This leads to pod unavailability until all masters are upgraded to new version.
To avoid implementing leader election in bash, results of leader election in kube-controller-manager are used. Long term, addon manager probably should be rewritten in a real prgramming language (probably Go), and then, real leader election should be implemented there.
**Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*:
I don't think there was an issue for this specifically, but this PR is related to https://github.com/kubernetes/kubernetes/issues/473
**Special notes for your reviewer**:
**Release note**:
```release-note
Addon manager supports HA masters.
