Fix error for strategic merge patch of custom resources
Fixes#50037.
We need the go struct tags `patchMergeKey` and `patchStrategy` for fields that support a strategic merge patch. For native resources, we can easily figure out these tags since we know the fields.
Because custom resources are decoded as Unstructured and because we're missing the metadata about how to handle each field in a strategic merge patch, we can't find the go struct tags. Hence, we can't easily do a strategic merge for custom resources.
So we should fail fast and return an error.

Use the core client with explicit version globally
**What this PR does / why we need it**:
As mentioned in #49535 and #50605, we want to have a global replace to use core client with explicit version.
**Which issue this PR fixes**: fixes#49535
**Special notes for your reviewer**:
The actual type of clientSet.Core() is already the same with clientSet.CoreV1(), so it should be safe replacement.
The places that clientSet.Core() are still in use are identified by IDE "find usages", and changes are made with one time global replace. Hopefully there will be none left after this PR merged.
Let me know if this PR is too big to review, I can split it into some smaller ones.

move webhook admission to generic apiserver
This builds on https://github.com/kubernetes/kubernetes/pull/54414.
It moves the admission webhook into the generic apiserver. It also allows the injection of a server managed way to override the rest.Config used for a particular service. This makes for an easier point to allow auto-configuration of the kube-apiserver to loopback to itself as a special case for kubernetes.default.svc.

Update rules_go, repo-infra, and rules_docker dependencies
**What this PR does / why we need it**: several of our bazel dependencies were getting pretty old, since they required bazel 0.5.4+ but there were various failures if we tried to use them with bazel 0.5.4.
Now that bazel 0.6.0 (and 0.6.1) have been out for a while, we can bump our dependencies and get a number of fixes and new functionality.
x-ref #52677 and others
**Special notes for your reviewer**:
* This will now explicitly require bazel 0.6.0+ to build kubernetes.
* Our staging directories are causing some issues for `gazelle`; it wants to set `importpath = "k8s.io/kubernetes/staging/src/k8s.io/blah"` instead of `importpath = "k8s.io/blah"`. I'm not sure what is the correct way to fix this; what we're doing here is pretty weird and nonstandard. I've used a `sed` substitution for now.
* The `-proto=default` option of `gazelle` has a number of bugs right now (https://github.com/bazelbuild/rules_go/issues/888, https://github.com/bazelbuild/rules_go/issues/900, https://github.com/bazelbuild/rules_go/issues/907), so I am forcing the legacy behavior.

Make feature gates loadable from a map[string]bool
Command line flag API remains the same. This allows ComponentConfig
structures (e.g. KubeletConfiguration) to express the map structure
behind feature gates in a natural way when written as JSON or YAML.
For example:
KubeletConfiguration Before:
```
apiVersion: kubeletconfig/v1alpha1
kind: KubeletConfiguration
featureGates: "DynamicKubeletConfig=true,Accelerators=true"
```
KubeletConfiguration After:
```
apiVersion: kubeletconfig/v1alpha1
kind: KubeletConfiguration
featureGates:
DynamicKubeletConfig: true
Accelerators: true
```
Fixes: #53024
```release-note
The Kubelet's feature gates are now specified as a map when provided via a JSON or YAML KubeletConfiguration, rather than as a string of key-value pairs.
```

Add an option for turning on/off compaction from apiserver in etcd3 mode
…erver
**What this PR does / why we need it**:
This commit adds an option for controlling request of compaction to
etcd3 from apiserver. There is a situation that apiserver cannot fully
own its etcd cluster (e.g. sharing it with canal). In such a case,
apiserver should have limited access in terms of etcd's auth
functionality so it don't have a privilege to issue compaction
requests. It means that the compaction requests should be issued by
other component and apiserver's compaction requests are needless.
For such use cases, this commit adds a new flag
storagebackend.Config.DoCompaction. If the flag is true (default),
apiserver issues the compaction requests like current behaviour. If it
is false, apiserver doesn't issue the requests.
**Related issue (etcd)**

update-staging-godeps: only mangle staging repos in staging Godeps.json

The first breaks k8s.io/kube-aggregator's staging export.

Improve apiserver metrics reporting
Normalize "WATCHLIST" to "WATCH", add "scope" to the other metrics (listing 50k pods is != listing pods in a namespace), and add a new scope "resource" to cover individual resource calls.
This roughly aligns metrics with our ACL model (technically resource scope is GET, but POST to a subresource and POST to a namespace are not the same thing).

WATCHLIST calls are now reported as WATCH verbs in prometheus for the apiserver_request_* series. A new "scope" label is added to all apiserver_request_* values that is either 'cluster', 'resource', or 'namespace' depending on which level the query is performed at.

apiservers: stratify versioned informer construction
The versioned share informer factory has been part of the GenericApiServer config,
but its construction depended on other fields of that config (e.g. the loopback
client config). Hence, the order of changes to the config mattered.
This PR stratifies this by moving the SharedInformerFactory from the generic Config
to the CompleteConfig struct. Hence, it is only filled during completion when it is
guaranteed that the loopback client config is set.
While doing this, the CompletedConfig construction is made more type-safe again,
i.e. the use of SkipCompletion() is considereably reduced. This is archieved by
splitting the derived apiserver Configs into the GenericConfig and the ExtraConfig
part. Then the completion is structural again because CompleteConfig is again
of the same structure: generic CompletedConfig and local completed ExtraConfig.
Fixes#50661.

Update Cadvisor Dependency
Fixes: https://github.com/kubernetes/kubernetes/issues/51832
This is the worst dependency update ever...
The root of the problem is the [name change of Sirupsen -> sirupsen](https://github.com/sirupsen/logrus/issues/570#issuecomment-313933276). This means that in order to update cadvisor, which venders the lowercase, we need to update all dependencies to use the lower-cased version. With that being said, this PR updates the following packages:
`github.com/docker/docker`
- `github.com/docker/distribution`
- `github.com/opencontainers/go-digest`

Kubectl to use http caching to cache openapi responses from the server
**What this PR does / why we need it**:
This PR is trying to address the problems raised in #50254
> * uses a disk-based cache that is not safe between processes (does not use atomic fs operations)
> * writes get/list responses to disk that should not be cached (like kubectl get secrets)
> * is vulnerable to partially written cache responses being used as responses to future requests
> * breaks uses of the client transport that make use of websockets
> * defaults to enabling the cache for any client builder using RecommendedConfigOverrideFlags or DefaultClientConfig which affects more components than just kubectl
All of these points are addressed by this pull-request:
1. It now uses atomic fs operations
2. Doesn't cache by default, only if requested by the client (and it's only done by openapi client)
3. Fixed because of atomic fs operations
4. Found the reason for the bug: Cache wrapper couldn't be unwrapped. I implemented the `WrappedRoundTripper` interface.
5. Since 2. is fixed, I think that should be fine

Remove null -> [] slice hack
Closes#44593
When 1.6 added protobuf storage, the storage layer lost the ability to persist slice fields with empty but non-null values.
As a workaround, we tried to convert empty slice fields to `[]`, rather than `null`. Compressing `null` -> `[]` was just as much of an API breakage as `[]` -> `null`, but was hoped to cause fewer problems in clients that don't do null checks.
Because of conversion optimizations around converting lists of objects, the `null` -> `[]` hack was discovered to only apply to individual get requests, not to a list of objects. 1.6 and 1.7 was released with this behavior, and the world didn't explode. 1.7 documented the breaking API change that `null` and `[]` should be considered equivalent, unless otherwise noted on a particular field.
This PR:
* Reverts the earlier attempt (https://github.com/kubernetes/kubernetes/pull/43422) at ensuring non-null json slice output in conversion
* Makes results of `get` consistent with the results of `list` (which helps naive clients that do deepequal comparisons of objects obtained via list/watch and get), and allows empty slice fields to be returned as `null`
```release-note
Protobuf serialization does not distinguish between `[]` and `null`.
API fields previously capable of storing and returning either `[]` and `null` via JSON API requests (for example, the Endpoints `subsets` field) can now store only `null` when created using the protobuf content-type or stored in etcd using protobuf serialization (the default in 1.6+). JSON API clients should tolerate `null` values for such fields, and treat `null` and `[]` as equivalent in meaning unless specifically documented otherwise for a particular field.
