Improve etcd-version-monitor metrics proxying, add etcd 3.1 gprc metr…
Partially addresses https://github.com/kubernetes/kubernetes/issues/56869:
- Fix `etcd-version-monitor` to support etcd 3.1: Add support for the etcd 3.1+ [go-grpc-prometheus](https://github.com/grpc-ecosystem/go-grpc-prometheus) metrics format, which backward incompatibly replaces the 3.0 legacy grpc metric format. Expose the go-grpc-prometheus metrics both in the 3.1 format and in the 3.0 format so systems consuming `etcd-version-monitor` metrics have a clean, simple upgrade path.
- Expose *all* etcd metrics by default, making this a one stop shop for all etcd metrics.
- Expose grpc request latency histogram metrics (`grpc_server_handling_seconds` from [go-grpc-prometheus](https://github.com/grpc-ecosystem/go-grpc-prometheus) metrics format). Rewrite etcd 3.0 legacy metric for latency histograms to the etcd 3.1+ `go-grpc-prometheus` format so there is a single format exported for all etcd versions.
etcd 3.0 to 3.1 upgrade path: Continue to use the `etcd_grpc_requests_total`. Once the upgrade is complete and all etcd nodes are running 3.1, migrate to the `grpc_server_handled_total` metric at your leisure.
This PR reorganizes the code substantially. Previously, the code to proxy etcd metrics was hard coded and limited to a single counter metric. This has been entirely replaced with code that generically filters, rewrites proxied etcd metrics and then aggregates them with custom metrics such as the etcd version metric.

We shouldn't upgrade etcd without first warning the user that some etcd
version transitions can't be undone. We don't know what version the user
currently has, so we require either an explicit version and image, or an

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.

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.

Run nvidia-gpu device-plugin daemonset as an addon on GCE nodes that have nvidia GPUs attached
- Instead of the old `Accelerators` feature that added `alpha.kubernetes.io/nvidia-gpu` resource, use the new `DevicePlugins` feature that adds vendor specific resources. (In case of nvidia GPUs it will
add `nvidia.com/gpu` resource.)
- Add node label to GCE nodes with accelerators attached. This node label is the same as what GKE attaches to node pools with accelerators attached. (For example, for nvidia-tesla-p100 GPU, the label would be `cloud.google.com/gke-accelerator=nvidia-tesla-p100`) This will help us target accelerator specific
daemonsets etc. to these nodes.
- Run nvidia-gpu device-plugin daemonset as an addon on GCE nodes that have nvidia GPUs attached.
- Some minor documentation improvements in addon manager.
**Release note**:
```release-note
GCE nodes with NVIDIA GPUs attached now expose `nvidia.com/gpu` as a resource instead of `alpha.kubernetes.io/nvidia-gpu`.

Add extra-args configs for scheduler and controller-manager to kubernetes-master charm
**What this PR does / why we need it**:
This adds `controller-manager-extra-args` and `scheduler-extra-args` config options to the kubernetes-master charm.
These allow operators of Juju-based Kubernetes clusters to pass arbitrary arguments to kube-controller-manager and kube-scheduler as needed.
**Release note**:
```release-note
Add extra-args configs for scheduler and controller-manager to kubernetes-master charm

Disable the grace termination period for the calico/node pod
**What this PR does / why we need it**:
Disable the termination grace period for the calico/node add-on DaemonSet. The grace period is unnecessary for calico/node and it delays restart of a new calico/node pod to take over routing and policy updates.
Setting the grace period to 0 has the special meaning of doing a force deletion, which avoids a slow round-trip through the kubelet and API server.

**Special notes for your reviewer**:
**Release note**:
```release-note

Remove Google Cloud KMS's in-tree integration
Removes the following introduced by #48574 and others:
* `kms.go` which contained the cloudkms-specific code for Google Cloud KMS service.
* Registering the Google Cloud KMS in the KMS plugin registry.
* Google's `cloudkms` API package from `vendor` folder.
The following changes are upcoming:
* Removal of KMSPluginRegistry. This would not be needed anymore, since KMS providers will be out-of-tree from now on (so no need of registering them, an address of the process would be enough).
* A service which allows encrypt/decrypt functionality (satisfies `envelope.Service` interface) if initialized with an IP/Port of an out-of-tree process serving KMS requests. Will tentatively use gRPC requests to talk to this external service.
Reference: https://github.com/kubernetes/kubernetes/pull/54439#issuecomment-340062801 and https://github.com/kubernetes/kubernetes/issues/51965#issuecomment-339333937.
```release-note
Google KMS integration was removed from in-tree in favor of a out-of-process extension point that will be used for all KMS providers.

Reduce metadata-proxy cpu requests to 30m
After the recent change enabling metadata-proxy in tests (https://github.com/kubernetes/kubernetes/pull/54150) we started seeing problems with scheduling cluster autoscaler on master. Metadata-proxy eats all of the available space leaving nothing for CA to run on.
This PR reduces the cpu requests for metadata-proxy allowing other components to fit in.

Add support to for alternative container runtime in `kube-up.sh`
For https://github.com/kubernetes/features/issues/286.
This PR added 4 new environment variables in `kube-up.sh` to support alternative container runtime:
1) `KUBE_MASTER_EXTRA_METADATA` and `KUBE_NODE_EXTRA_METADATA`. Add extra metadata on master and node instance. With this we could specify different cloud-init for a different container runtime, and also add extra metadata for the new cloud-init, e.g. [master.yaml](7d73966214/test/e2e/master.yaml)
2) `KUBE_CONTAINER_RUNTIME_ENDPOINT`. Specify different sock for different container runtime. It's only used when it's not empty.
3) `KUBE_LOAD_IMAGE_COMMAND`. Specify different load image command for different container runtime.
An example for cri-containerd:
```
export KUBE_MASTER_EXTRA_METADATA="user-data=${GOPATH}/src/github.com/kubernetes-incubator/cri-containerd/test/e2e/master.yaml,cri-containerd-configure-sh=${GOPATH}/src/github.com/kubernetes-incubator/cri-containerd/test/configure.sh"
export KUBE_NODE_EXTRA_METADATA="user-data=${GOPATH}/src/github.com/kubernetes-incubator/cri-containerd/test/e2e/node.yaml,cri-containerd-configure-sh=${GOPATH}/src/github.com/kubernetes-incubator/cri-containerd/test/configure.sh"
export KUBE_CONTAINER_RUNTIME="remote"
export KUBE_CONTAINER_RUNTIME_ENDPOINT="/var/run/cri-containerd.sock"
export KUBE_LOAD_IMAGE_COMMAND="/home/cri-containerd/usr/local/bin/cri-containerd load"
export NETWORK_POLICY_PROVIDER="calico"
