There is no use case known for passing artifacts per device as it currently exists. The current API is also
complex to use for simple clients. Hence this PR creates a flat namespace where artifacts like environment variables
and mount points apply globally to all devices returned as part of AllocateResponse proto.

pkg/api: extract Scheme/Registry/Codecs into pkg/api/legacyscheme
This serves as
- a preparation for the pkg/api->pkg/apis/core move
- and makes the dependency to the scheme explicit when vizualizing
left depenncies.
The later helps with our our efforts to split up the monolithic repo
into self-contained sub-repos, e.g. for kubectl, controller-manager
and kube-apiserver in the future.

fix PV Recycle issue when running on multi-arch
**What this PR does / why we need it**:
Currently PV Recycle uses image `gcr.io/google_containers/busybox`, which is an amd64 image, not applied for multi-arch , to start pod `"pv-recycler"`. For other non-x86 platforms, like `ppc64le` and `arm64`, the pod cannot get started due to the busybox image.

Provide aggregated validation errors for version and kind
Currently the validation checks is done individually for version and
kind group. For example, if user provided yaml file is missing apiVersion
and kind fields, first they will receive error on apiVersion. Once user
update the file and try to recreate, an error on missing kind is displayed.
The behavior is same for wrong types of the fields.
These errors should be aggregated and displayed.
Examples of current validation:
1
test.yaml is missing apiVersion and kind:
$kubectl.sh create -f /home/sahdev/go/src/bugfixes/test.yaml
error: error validating "/home/sahdev/go/src/bugfixes/test.yaml": error validating data: apiVersion not set; if you choose to ignore these errors, turn validation off with --validate=false
2.
test.yaml is fixed for apiVersion but missing kind:
$kubectl.sh create -f /home/sahdev/go/src/bugfixes/test.yaml
error: error validating "/home/sahdev/go/src/bugfixes/test.yaml": error validating data: kind not set; if you choose to ignore these errors, turn validation off with --validate=false
Examples with aggregated validation:
1.
error: error validating "/home/sahdev/go/src/bugfixes/test.yaml": error validating data: [apiVersion not set, kind not set]; if you choose to ignore these errors, turn validation off with --validate=false
2.
error: error validating "/home/sahdev/go/src/bugfixes/testmix.yaml": error validating data: [apiVersion isn't string type, kind not set]; if you choose to ignore these errors, turn validation off with --validate=false
**What this PR does / why we need it**:

Get fallback termination msg from docker when using journald log driver
**What this PR does / why we need it**:
When using the legacy docker container runtime and when a container has `terminationMessagePolicy=FallbackToLogsOnError` and when docker is configured with a log driver other than `json-log` (such as `journald`), the kubelet should not try to get the container's log from the json log file (since it's not there) but should instead ask docker for the logs.

Clean up kublet secret and configmap unit test
**What this PR does / why we need it**:
These changes are clean-up items to fix confusing code encountered while investigating #52043. No actual bugs are fixed here (except, maybe, correcting unit tests that had actual/expected swapped).
A summary of the changes, as listed in the commit:
* Expected value comes before actual value in assert.Equal()
* Use `assert.Equal()` instead of `assert.True()` when possible
* Add a unit test that verifies no-op pod updates to the `secret_manager` and the `configmap_manager`
* Add a clarifying comment about why it's good to seemingly delete a secret on updates.
* Fix (for now, non-buggy) variable shadowing issue

Order PSP by name, prefer non-mutating PSPs
Fixes#36184Fixes#23217
Related to #23217
Removes unnecessary mutation of pods:
* Determines effective security context for pods using a wrapper containing the pod and container security context, rather than building/setting a combined struct on every admission
* Does not set `privileged:&false` on security contexts with `privileged:nil`
* Does not set `runAsNonRoot:&true` on security contexts that already have a non-nil, non-0 `runAsUser`
* Does not mutate/normalize container capabilities unless changes are required (missing defaultAddCapabilities or requiredDropCapabilities)
Defines behavior when multiple PSP objects allow a pod:
* PSPs which allow the pod as-is (no defaulting/mutating) are preferred
* If the pod must be defaulted/mutated to be allowed, the first PSP (ordered by name) to allow the pod is selected
* During update operations, when mutations to pod specs are disallowed, only non-mutating PSPs are used to validate the pod
```release-note
PodSecurityPolicy: when multiple policies allow a submitted pod, priority is given to ones which do not require any fields in the pod spec to be defaulted. If the pod must be defaulted, the first policy (ordered by name) that allows the pod is used.

In the testing of a manually created k8s cluster, I found controller manager on master would crash in current scenario:
1. Use acs-engine to set up k8s 1.7.7 cluster (it's with an availability set)
2. Manually add a node to the k8s cluster (without an availibity set in this VM)
3. Set up a service and schedule the pod onto this newly added node
4. controller manager would crash on master because although this k8s cluster has an availability set, the newly added node's `machine.AvailabilitySet` is nil which would cause controller manager crash

Prevent a Kubelet from shutting down when the server isn't responding to
us but we cannot get a new certificate. This allows a cluster to coast
if the master is unresponsive or a node is partitioned and their client
cert expires.
