Improve an error message when privileged containers are disallowed on the cluster
**What this PR does / why we need it**:
At present when user creates privileged pod and creation of privileged containers disallowed globally by a system administrator (kubelet and api-server were running with `--allow-privileged=false`), user will get the following error message:
```console
$ kubectl create -f nginx.pod
The Pod "nginx" is invalid: spec.containers[0].securityContext.privileged: Forbidden: disallowed by policy
```
"Disallowed by policy" may give a wrong assumption to a user that creation of privileged containers disallowed by [`PodSecurityPolicy`](http://kubernetes.io/docs/user-guide/pod-security-policy/) while it's not.
This commit improves error message and tries to point user to the right direction:
```console

Priority REST Mapper: Actually honor user choice
```release-note
Fixes bug in resolving client-requested API versions
```
RESTMapping takes a desired GroupKind, and a set of versions, and
returns a rest mapper for the first matching version. It also has a
list of built-in discovered prioritized versions, to which it appends
the user versions.
However, when it goes to parse the versions, it parses them as
GroupVersions. Since only a version was passed, the group will be the
empty group (""), which will only match rest mappings for the empty
group, ergo, none of the user's versions will match if they are
attempting a match for a non-emtpy-group GroupKind.
This fixes that by taking the parsed GroupVersion, and overriding the
Group with the Group from the passed-in GroupKind.

RESTMapping method can now rely on RESTMappings by passing versions parameter and taking the first match found by RESTMappings method. In addition
a UT that test the new method has been added.
The only change in logic to what was before is when calling RESTMapping
we search all defaultGroupVersion as opposed to just one when no mapping was found for provided versions.

Test 0-length-arrays in fuzzing tests
While hacking on #37289 I noticed that our fuzzing tests test nil slices and slices of length 1, but not slices of length 0, meaning we aren't testing that 0-length slices get treated the same as nil in all the places we expect them to (and in particular, we aren't ensuring that comparisons always use api.Semantic.DeepEqual rather than reflect.DeepEqual). (Though in fact, changing the fuzzer didn't turn up any bugs, so maybe this effectively gets tested somewhere else...)
`fuzz.New().NilChance(.5).NumElements(0, 1)` means we end up generating `nil` 50% of the time, a length 0 array 25% of the time, and a length 1 array 25% of the time... maybe it should be `fuzz.New().NilChance(.33).NumElements(0, 1)` instead?

Curating Owners: pkg/api
cc @lavalamp @smarterclayton @erictune @thockin @bgrant0607
In an effort to expand the existing pool of reviewers and establish a
two-tiered review process (first someone lgtms and then someone
experienced in the project approves), we are adding new reviewers to
existing owners files.
If You Care About the Process:
------------------------------
We did this by algorithmically figuring out who’s contributed code to
the project and in what directories. Unfortunately, that doesn’t work
well: people that have made mechanical code changes (e.g change the
copyright header across all directories) end up as reviewers in lots of
places.
Instead of using pure commit data, we generated an excessively large
list of reviewers and pruned based on all time commit data, recent
commit data and review data (number of PRs commented on).
At this point we have a decent list of reviewers, but it needs one last
pass for fine tuning.
Also, see https://github.com/kubernetes/contrib/issues/1389.
TLDR:
-----
As an owner of a sig/directory and a leader of the project, here’s what
we need from you:
1. Use PR https://github.com/kubernetes/kubernetes/pull/35715 as an example.
2. The pull-request is made editable, please edit the `OWNERS` file to
remove the names of people that shouldn't be reviewing code in the
future in the **reviewers** section. You probably do NOT need to modify
the **approvers** section. Names asre sorted by relevance, using some
secret statistics.
3. Notify me if you want some OWNERS file to be removed. Being an
approver or reviewer of a parent directory makes you a reviewer/approver
of the subdirectories too, so not all OWNERS files may be necessary.
4. Please use ALIAS if you want to use the same list of people over and
over again (don't hesitate to ask me for help, or use the pull-request
above as an example)

[RFC] Prepare for deprecating NodeLegacyHostIP

*What this PR does*
- Add comments saying "LegacyHostIP" will be deprecated in 1.7;
- Add v1.NodeLegacyHostIP to be consistent with the internal API (useful for client-go migration #35159)
- Let cloudproviders who used to only set LegacyHostIP set the IP as both InternalIP and ExternalIP
- Master used to ssh tunnel to node's ExternalIP or LegacyHostIP to do [healthz check](https://github.com/kubernetes/kubernetes/blame/master/pkg/master/master.go#L328-L332). OTOH, if on-prem, kubelet only [sets](https://github.com/kubernetes/kubernetes/blob/master/pkg/kubelet/kubelet_node_status.go#L430-L431) LegacyHostIP or InternalIP. In order to deprecate LegacyHostIP in 1.7, I let healthz check to use InternalIP if ExternalIP is not available. (The healthz check is the only consumer of LegacyHostIP in k8s.)

This is the first stab at getting the Kubelet running on Windows (fixes#30279), and getting it to deploy network-accessible pods that consist of Windows containers. Thanks @csrwng, @jbhurat for helping out.
The main challenge with Windows containers at this point is that container networking is not supported. In other words, each container in the pod will get it's own IP address. For this reason, we had to make a couple of changes to the kubelet when it comes to setting the pod's IP in the Pod Status. Instead of using the infra-container's IP, we use the IP address of the first container.
Other approaches we investigated involved "disabling" the infra container, either conditionally on `runtime.GOOS` or having a separate windows-docker container runtime that re-implemented some of the methods (would require some refactoring to avoid maintainability nightmare).
Other changes:
- The default docker endpoint was removed. This results in the docker client using the default for the specific underlying OS.
More detailed documentation on how to setup the Windows kubelet can be found at https://docs.google.com/document/d/1IjwqpwuRdwcuWXuPSxP-uIz0eoJNfAJ9MWwfY20uH3Q.

Avoid double decoding all client responses
Fixes#35982
The linked issue uncovered that we were always double decoding the response in restclient for get, list, update, create, and patch. That's fairly expensive, most especially for list. This PR refines the behavior of the rest client to avoid double decoding, and does so while minimizing the changes to rest client consumers.
restclient must be able to deal with multiple types of servers. Alter the behavior of restclient.Result#Raw() to not process the body on error, but instead to return the generic error (which still matches the error checking cases in api/error like IsBadRequest). If the caller uses
.Error(), .Into(), or .Get(), try decoding the body as a Status.
For older servers, continue to default apiVersion "v1" when calling restclient.Result#Error(). This was only for 1.1 servers and the extensions group, which we have since fixed.
This removes a double decode of very large objects (like LIST) - we were trying to DecodeInto status, but that ends up decoding the entire result and then throwing it away. This makes the decode behavior specific to the type of action the user wants.
```release-note
The error handling behavior of `pkg/client/restclient.Result` has changed. Calls to `Result.Raw()` will no longer parse the body, although they will still return errors that react to `pkg/api/errors.Is*()` as in previous releases. Callers of `Get()` and `Into()` will continue to receive errors that are parsed from the body if the kind and apiVersion of the body match the `Status` object.
This more closely aligns rest client as a generic RESTful client, while preserving the special Kube API extended error handling for the `Get` and `Into` methods (which most Kube clients use).

Simplify negotiation in server in preparation for multi version support
This is a pre-factor for #33900 to simplify runtime.NegotiatedSerializer, tighten up a few abstractions that may break when clients can request different client versions, and pave the way for better negotiation.
View this as pure simplification.
- Prevents kubelet from overwriting capacity during sync.
- Handles opaque integer resources in the scheduler.
- Adds scheduler predicate tests for opaque resources.
- Validates opaque int resources:
- Ensures supplied opaque int quantities in node capacity,
node allocatable, pod request and pod limit are integers.
- Adds tests for new validation logic (node update and pod spec).
- Added e2e tests for opaque integer resources.
Alter how runtime.SerializeInfo is represented to simplify negotiation
and reduce the need to allocate during negotiation. Simplify the dynamic
client's logic around negotiating type. Add more tests for media type
handling where necessary.

The number of values for a given label is generally pretty small (in huge majority of cases it is exactly one value).
Currently computing selectors is up to 50% of CPU usage in both apiserver and scheduler.

Split conversion and defaulting
Separate conversion and defaulting. Defaulting occurs mixed with conversion today - change the server so that the `VersioningCodec` performs defaulting on the external type during decoding.
* Add a new method to `Scheme` - `func (*runtime.Scheme) Default(runtime.Object)` - that takes an object and performs defaulting.
* Call `Default` during decoding and at static initialization time
* Use the new `defaulter-gen` to generate top level object defaulters (`v1.Pod`) at build time for any type that needs to perform defaulting.
* Add tests and alter the existing code to adapt as necessary
* Fix a few bugs in conversions that depended on defaulting behavior
---
Step 1 of decoupling conversion and defaulting. The generator will assist in creating top level defaulters that in a single method invoke all nested defaulters, preventing the need to recurse via reflection or conversion. These top level defaulters will be registered in the scheme and invoked instead of the nested recursion path. This will set the stage for a future generator, capable of creating defaulters from embedded struct tags on external types. However, we must gradually switch these over.
The immediate goal here is to split defaulting and conversion so that the unsafe convertor can be used to maximum potential (we would be able to use direct memory conversion for any identical nested struct, even those that must be defaulted).
The generator uses `k8s:defaulter-gen=TypeMeta` on most public packages to flag any top level type that has defaulters to get a `SetObjectDefaults_NAME` function created (types that don't have defaulters won't have functions). This also creates a `RegisterDefaults` method that applies a default to an interface{} and returns true if the object was handled. Existing defaults are left as is.
Add a test to verify old and new path generate the same outcomes. Defaulter will move to gengo before this is merged, and subsequent PRs will remove defaulting during conversion and have the VersioningCodec apply defaults.
Most normal codec use should perform defaulting. DirectCodecs should not
perform defaulting. Update the defaulting_test to fuzz the list of known
defaulters. Use the new versioning.NewDefaultingCodec() method.

Add PSP support for seccomp profiles
Seccomp support for PSP. There are still a couple of TODOs that need to be fixed but this is passing tests.
One thing of note, since seccomp is all being stored in annotations right now it breaks some of the assumptions we've stated for the provider in terms of mutating the passed in pod. I've put big warning comments around the pieces that do that to make sure it's clear and covered the rollback in admission if the policy fails to validate.

Add PVC storage to LimitRange
This PR adds the ability to add a LimitRange to a namespace that enforces min/max on `pvc.Spec.Resources.Requests["storage"]`.
@derekwaynecarr @abhgupta @kubernetes/sig-storage
Examples forthcoming.
```release-note
pvc.Spec.Resources.Requests min and max can be enforced with a LimitRange of type "PersistentVolumeClaim" in the namespace

Match GroupVersionKind against specific version
Currently when multiple GVK match a specific kind in `KindForGroupVersionKinds` only the first will be matched, which not necessarily will be the correct one. I'm proposing to extend this to pick the best match, instead.
Here's my problematic use-case, of course it involves ScheduledJobs 😉:
I have a `GroupVersions` with `batch/v1` and `batch/v2alpha1` in that order. I'm calling `KindForGroupVersionKinds` with kind `batch/v2alpha1 ScheduledJob` and that currently results this matching first `GroupVersion`, instead of picking more concrete one. There's a [clear description](ee77d4e6ca/pkg/api/unversioned/group_version.go (L183)) why it is on single `GroupVersion`, but `GroupVersions` should pick this more carefully.
@deads2k this is your baby, wdyt?
Contination of #1111
I tried to keep this PR down to just a simple search-n-replace to keep
things simple. I may have gone too far in some spots but its easy to
roll those back if needed.
I avoided renaming `contrib/mesos/pkg/minion` because there's already
a `contrib/mesos/pkg/node` dir and fixing that will require a bit of work
due to a circular import chain that pops up. So I'm saving that for a
follow-on PR.
I rolled back some of this from a previous commit because it just got
to big/messy. Will follow up with additional PRs

Revert "Work around the etcd watch issue"
Reverts kubernetes/kubernetes#33101
Since #33393 is merged, the bug should have been fixed.
We had another bug where we confused the hostname with the NodeName.
To avoid this happening again, and to make the code more
self-documenting, we use types.NodeName (a typedef alias for string)
whenever we are referring to the Node.Name.
A tedious but mechanical commit therefore, to change all uses of the
node name to use types.NodeName
Also clean up some of the (many) places where the NodeName is referred
to as a hostname (not true on AWS), or an instanceID (not true on GCE),
etc.
* flocker datasets should be attached using an unique identifier. This
is not the case for the name metadata used by datasetName
* allow only one of datasetUUID / datasetName specified

Allow garbage collection to work against different API prefixes
The GC needs to build clients based only on Resource or Kind. Hoist the
restmapper out of the controller and the clientpool, support a new
ClientForGroupVersionKind and ClientForGroupVersionResource, and use the
appropriate one in both places.

unify available api group versions in our scripts
There are currently many parallel lists of available group versions with slightly different syntaxes in each one. This collapses them into a single list for us to maintain.
Also caught spots where the lists didn't match before.
