[Federation] Create configmap for the cluster kube-dns when cluster joins and remove when it unjoins
This PR implements the functionality as needed in https://github.com/kubernetes/kubernetes/issues/38400
cc @kubernetes/sig-cluster-federation @nikhiljindal @madhusudancs
**Release note**:
```
kubefed join can now automatically create a configmap or add information to already existing one, storing this federation name vs zone name information in the joining cluster.
Further kubefed unjoin can remove this configmap or only this information from the configmap, if the unjoin cluster is registered with multiple federations.
The name of the configmap is kube-dns and the information in it is consumed by the in-cluster dns server.

Juju: Fix shebangs in charm actions to use python3
**What this PR does / why we need it**:
This fixes the microbot and create-rbd-pv actions by reverting them back to python3. We accidentally switched them to python2 to match the boilerplate checker's expectations for python files.
It looks like hack/verify-boilerplate.sh does not check these since they don't have the .py extension, so we should be good with no changes there.

PV upgrade test
**What this PR does / why we need it**:
This PR adds a PV upgrade test to the new upgrade test framework. Before, this test had to be done manually.

Use docker log rotation mechanism instead of logrotate
This is a solution for https://github.com/kubernetes/kubernetes/issues/38495.
Instead of rotating logs using logrotate tool, which is configured quite rigidly, this PR makes docker responsible for the rotation and makes it possible to configure docker logging parameters. It solves the following problems:
* Logging agent will stop loosing lines upon rotation
* Container's logs size will be more strictly constrained. Instead of checking the size hourly, size will be checked upon write, preventing https://github.com/kubernetes/kubernetes/issues/27754
It's still far from ideal, for example setting logging options per pod, as suggested in https://github.com/kubernetes/kubernetes/issues/15478 would be much more flexible, but latter approach requires deep changes, including changes in API, which may be in vain because of CRI and long-term vision for logging.
Changes include:
* Change in salt. It's possible to configure docker log parameters, using variables in pillar. They're exported from env variables on `gce`, but for different cloud provider they have to be exported first.
* Change in `configure-helper.sh` scripts for those os on `gce` that don't use salt + default values exposed via env variables
This change may be problematic for kubelet logs functionality with CRI enabled, that will be tackled in the follow-up PR, if confirmed.
CC @piosz @Random-Liu @yujuhong @dashpole @dchen1107 @vishh @kubernetes/sig-node-pr-reviews
```release-note
On GCI by default logrotate is disabled for application containers in favor of rotation mechanism provided by docker logging driver.

Cleanup fluentd-gcp image, rebase on debian-base
**Why we need this PR**:
There are several problems with our current fluentd-gcp image:
- It pulls in lots of unused packages, which expose unnecessary risk and create noise in CVE scans (and scare customers). The most notable example is the fluent-ui, which pulls in rails.
- `curl | sh ` is not a good practice for a Dockerfile. First, the script is not checked in the same source control branch, so builds are not reproducible. Second, the actions it is taking are opaque. Third, in this case, using non-standard packages means they're harder to manage with CVE scans & upstream fixes.
**What is changed by this PR?**
- Rather than relying on td-agent (which includes fluent-ui), use standard upstream packages. This is largely based off the [official fluentd debian-based image](https://github.com/fluent/fluentd-docker-image/blob/master/v0.12/debian/Dockerfile).
- Rebases the image on debian-base (depends on https://github.com/kubernetes/kubernetes/pull/41915). We would like to move towards a single full-distro base image we can maintain. This change should be relatively minor.
As a result of these changes, the image size is reduced from 360.6 MB to 185.8 MB (nearly half). Many packages were removed, and the full diff (focus on the unversioned files) is listed here: 3fb704f977
**Which issue this PR fixes** https://github.com/kubernetes/kubernetes/issues/40248
**Special notes for your reviewer**:
This change both addresses security concerns, and is expected to greatly reduce the maintenance burden of the fluentd-gcp image. I'd *really* like to get this into 1.6, so please prioritize this review if possible.
I tested this by running the default e2e suite on a private e2e cluster using the new image. If there are other tests you'd like me to run, please let me know ASAP.
**Release note**:
```release-note
Cleanup fluentd-gcp image: rebase on debian-base, switch to upstream packages, remove fluent-ui & rails

Standard Debian base image
**What this PR does / why we need it**:
The goal of this new image is to provide a standard base image for Kubernetes system images that require substantial external dependencies (e.g. kube-proxy and fluentd). The image is significantly reduced from the standard `debian:jessie-slim` image (40 MB vs 80 MB), and removes a number of unnecessary dependencies such as e2fsprogs, systemd, and sysv-rc. In the future we may consider further reducing it to the bare minimum to run the package manager, with the requirement that images based on it add all the dependencies they need.
I tested this by rebasing kube-proxy on this image and running the e2e tests. I'm targeting 1.6 for rebasing kube-proxy & fluentd on this.
For the rational behind basing on Debian, see https://github.com/kubernetes/kubernetes/issues/40248#issuecomment-280781931

Updating kubectl to send delete requests with orphanDependents=false if --cascade is true
Ref https://github.com/kubernetes/kubernetes/issues/40568#38897
Updating kubectl to always set `DeleteOptions.orphanDependents=false` when deleting a resource with `--cascade=true`.
This is primarily for federation where we want to use server side cascading deletion.
Impact on kubernetes: kubectl will do another GET after sending a DELETE and wait till the resource is actually deleted. This can have an impact if the resource has a finalizer. kubectl will wait till the finalizer is removed and then the resource is deleted, which is the right thing to do but a notable change in behavior.

Guaranteed admission for Critical Pods
This is the first step in implementing node-level preemption for critical pods.
It defines the AdmissionFailureHandler interface, which allows callers, like the kubelet, to define how failed predicates are handled, and take steps to correct failures if necessary.
In the kubelet's implementation, it triggers preemption if the pod being admitted is critical, and if the only failed predicates are InsufficientResourceErrors, then it prempts (not yet implemented) other other pods to allow admission of the critical pod.

The current version of the inode eviction test only makes sure that the two abusive pods are evicted before the innocent pod. This change adds a check during the post-eviction monitoring period to ensure that the innocent pod is not evicted, even after the abusive pods.
This will likely result in a higher failure rate for this test, but since it is in the flaky test suite, this is not an issue.

Add namespaced role to inspect particular configmap for delegated authentication
Builds on https://github.com/kubernetes/kubernetes/pull/41814 and https://github.com/kubernetes/kubernetes/pull/41922 (those are already lgtm'ed) with the ultimate goal of making an extension API server zero-config for "normal" authentication cases.
This part creates a namespace role in `kube-system` that can *only* look the configmap which gives the delegated authentication check. When a cluster-admin grants the SA running the extension API server the power to run delegated authentication checks, he should also bind this role in this namespace.
@sttts Should we add a flag to aggregated API servers to indicate they want to look this up so they can crashloop on startup? The alternative is sometimes having it and sometimes not. I guess we could try to key on explicit "disable front-proxy" which may make more sense.

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.
