kubelet: enable qos-level memory limits
```release-note
Experimental support to reserve a pod's memory request from being utilized by pods in lower QoS tiers.
```
Enables the QoS-level memory cgroup limits described in https://github.com/kubernetes/community/pull/314
**Note: QoS level cgroups have to be enabled for any of this to take effect.**
Adds a new `--experimental-qos-reserved` flag that can be used to set the percentage of a resource to be reserved at the QoS level for pod resource requests.
For example, `--experimental-qos-reserved="memory=50%`, means that if a Guaranteed pod sets a memory request of 2Gi, the Burstable and BestEffort QoS memory cgroups will have their `memory.limit_in_bytes` set to `NodeAllocatable - (2Gi*50%)` to reserve 50% of the guaranteed pod's request from being used by the lower QoS tiers.
If a Burstable pod sets a request, its reserve will be deducted from the BestEffort memory limit.
The result is that:
- Guaranteed limit matches root cgroup at is not set by this code
- Burstable limit is `NodeAllocatable - Guaranteed reserve`
- BestEffort limit is `NodeAllocatable - Guaranteed reserve - Burstable reserve`
The only resource currently supported is `memory`; however, the code is generic enough that other resources can be added in the future.

Juju: Disable anonymous auth on kubelet
**What this PR does / why we need it**:
This disables anonymous authentication on kubelet when deployed via Juju.
I've also adjusted a few other TLS options for kubelet and kube-apiserver. The end result is that:
1. kube-apiserver can now authenticate with kubelet
2. kube-apiserver now verifies the integrity of kubelet

kubeadm: Rename some flags for beta UI and fixup some logic
**What this PR does / why we need it**:
In this PR:
- `--api-advertise-addresses` becomes `--apiserver-advertise-address`
- The API Server's logic here is that if the address is `0.0.0.0`, it chooses the host's default interface's address. kubeadm here uses exactly the same logic. This arg is then passed to `--advertise-address`, and the API Server will advertise that one for the service VIP.
- `--api-port` becomes `--apiserver-bind-port` for clarity

This commit switches over the HPA controller to use the custom metrics
API. It also converts the HPA controller to use the generated client
in k8s.io/metrics for the resource metrics API.
In order to enable support, you must enable
`--horizontal-pod-autoscaler-use-rest-clients` on the
controller-manager, which will switch the HPA controller's MetricsClient
implementation over to use the standard rest clients for both custom
metrics and resource metrics. This requires that at the least resource
metrics API is registered with kube-aggregator, and that the controller
manager is pointed at kube-aggregator. For this to work, Heapster
must be serving the new-style API server (`--api-server=true`).

Extend experimental support to multiple Nvidia GPUs
Extended from #28216
```release-note
`--experimental-nvidia-gpus` flag is **replaced** by `Accelerators` alpha feature gate along with support for multiple Nvidia GPUs.
To use GPUs, pass `Accelerators=true` as part of `--feature-gates` flag.
Works only with Docker runtime.
```
1. Automated testing for this PR is not possible since creation of clusters with GPUs isn't supported yet in GCP.
1. To test this PR locally, use the node e2e.
```shell
TEST_ARGS='--feature-gates=DynamicKubeletConfig=true' FOCUS=GPU SKIP="" make test-e2e-node
```
TODO:
- [x] Run manual tests
- [x] Add node e2e
- [x] Add unit tests for GPU manager (< 100% coverage)

add kubectl can-i to see if you can perform an action
Adds `kubectl auth can-i <verb> <resource> [<name>]` so that a user can see if they are allowed to perform an action.
@kubernetes/sig-cli-pr-reviews @fabianofranz
This particular command satisfies the immediate need of knowing if you can perform an action without trying that action. When using RBAC in a script that is adding permissions, there is a lag between adding the permission and the permission being realized in the RBAC cache. As a user on the CLI, you almost never see it, but as a script adding a binding and then using that new power, you hit it quite often.
There are natural follow-ons to the same area (hence the `auth` subcommand) to figure out if someone else can perform an action, what actions you can perform in total, and who can perform a given action. Someone else is an API we have already, what-can-i-do was a proposed API a while back and a very useful one for interfaces, and who-can is common question if someone is administering a namespace.

This adds a new stand-alone certificates controller for use on GKE. It

private key locally.
It does not aim for 100% feature parity with kube-controller-manager
yet, so for instance, leader election support is omitted.

Added a basic monitor for providing etcd version related info
Fixes#41071
This tool scrapes metrics partly from etcd's /version and /metrics endpoints and partly using etcdctl and exposes them as prometheus metrics at `http://localhost:9101/metrics` endpoint on the master. Here is a summary of the metrics it exposes (self-explanatory from the code):
- etcdVersionFetchCount = prometheus.NewCounterVec(
prometheus.CounterOpts{
Namespace: "etcd",
Name: "version_info_fetch_count",
Help: "Number of times etcd's version info was fetched, labeled by etcd's server binary and cluster version",

cluster/gce: Add env var to enable apiserver basic audit log.
For now, this is focused on a fixed set of flags that makes the audit
log show up under /var/log/kube-apiserver-audit.log and behave similarly
to /var/log/kube-apiserver.log. Allowing other customization would
require significantly more complex changes.
Audit log rotation is handled the same as for `kube-apiserver.log`.
**What this PR does / why we need it**:
Add a knob to enable [basic audit logging](https://kubernetes.io/docs/admin/audit/) in GCE.
**Which issue this PR fixes**:
**Special notes for your reviewer**:
We would like to cherrypick/port this to release-1.5 also.
**Release note**:
```release-note
The kube-apiserver [basic audit log](https://kubernetes.io/docs/admin/audit/) can be enabled in GCE by exporting the environment variable `ENABLE_APISERVER_BASIC_AUDIT=true` before running `cluster/kube-up.sh`. This will log to `/var/log/kube-apiserver-audit.log` and use the same `logrotate` settings as `/var/log/kube-apiserver.log`.
```
This change makes kubelet to use the CRI implementation by default,
unless the users opt out explicitly by using --enable-cri=false.
For the rkt integration, the --enable-cri flag will have no effect
since rktnetes does not use CRI.
Also, mark the original --experimental-cri flag hidden and deprecated,
so that we can remove it in the next release.
For now, this is focused on a fixed set of flags that makes the audit
log show up under /var/log/kube-apiserver-audit.log and behave similarly

Audit log rotation is handled externally by the wildcard /var/log/*.log
already configured in configure-helper.sh.

Splitting master/node services into separate charm layers

- Support for durable storage provided by Ceph

drift!)
- An e2e charm-layer to make running validation tests much simpler/repeatable
- Changes to support the 1.5.x series of Kubernetes

Coreos kube-up now with less cloud init
This update includes significant refactoring. It moves almost all of the
logic into bash scripts, modeled after the `gci` cluster scripts.
The reason to do this is:
1. Avoid duplicating the saltbase manifests by reusing gci's parsing logic (easier maintenance)
2. Take an incremental step towards sharing more code between gci/trusty/coreos, again for better maintenance
3. Pave the way for making future changes (e.g. improved rkt support, kubelet support) easier to share
The primary differences from the gci scripts are the following:
1. Use of the `/opt/kubernetes` directory over `/home/kubernetes`
2. Support for rkt as a runtime
3. No use of logrotate
4. No use of `/etc/default/`
5. No logic related to noexec mounts or gci-specific firewall-stuff
It will make sense to move 2 over to gci, as well as perhaps a few other small improvements. That will be a separate PR for ease of review.
Ref #29720, this is a part of that because it removes a copy of them.
Fixes#24165

Since this logic largely duplicates logic from the gci folder, it would be nice if someone closely familiar with that gave an OK or made sure I didn't fall into any gotchas related to that, so cc @andyzheng0831
