Add a new conversion path to replace GenericConversionFunc
reflect.Call is very expensive. We currently use a switch block as part of AddGenericConversionFunc to avoid the bulk of top level a->b conversion for our primary types which is hand-written. Instead of having these be handwritten, we should generate them.
The pattern for generating them looks like:
```
scheme.AddConversionFunc(&v1.Type{}, &internal.Type{}, func(a, b interface{}, scope conversion.Scope) error {
return Convert_v1_Type_to_internal_Type(a.(*v1.Type), b.(*internal.Type), scope)
})
```
which matches AddDefaultObjectFunc (which proved out the approach last year). The
conversion machinery should then do a simple map lookup based on the incoming types and invoke the function. Like defaulting, it's up to the caller to match the types to arguments, which we do by generating this code. This bypasses reflect.Call and in the future allows Golang mid-stack inlining to optimize this code.
As part of this change I strengthened registration of custom functions to be generated instead of hand registered, and also strengthened error checking of the generator when it sees a manual conversion to error out. Since custom functions are automatically used by the generator, we don't really have a case for not registering the functions.
Once this is fully tested out, we can remove the reflection based path and the old registration methods, and all conversion will work from point to point methods (whether generated or custom).
Much of the need for the reflection path has been removed by changes to generation (to omit fields) and changes to Go (to make assigning equivalent structs easy).

Fixing comments in types.go to describe the changes for CSI driver default FS type override fix
This PR fixes the comment in types.go which was made in the commit 5dfe7b5758
In the above commit, the change that fixed the override of default FSType for CSI driver was made. However the comments in types.go were made for GCEPersistentDiskVolumeSource and RBDVolumeSource respectively. This commit fixes that comment to reflect the changes for CSI driver

Bugfix/csi default fs type
This PR address the issue mentioned in the following ticket https://github.com/kubernetes/kubernetes/issues/65122
The FSType string will now not be defaulted to ext4. Removes defaulting of CSI file system type to ext4. CSI plugins that depended on this default need to be updated as the fsType would remain an empty string if not provided and would not default to ext4. CSI spec allows for an empty fstype string. This is intended for non-block plugins like nfs and gluster where filesystems are not separately created on the volume. But currently the default file system is overridden to ext4 which makes the above case redundant. This commit prevents such an overridding.
```release-note
ACTION REQUIRED: Removes defaulting of CSI file system type to ext4. All the production drivers listed under https://kubernetes-csi.github.io/docs/Drivers.html were tested and work as expected after this change. If you are using a driver not in that list, please test the drivers on an updated test cluster first. ```

apiextensions: add ObjectMeta validation and pruning
This is a critical pre-requisite for further multi-version support and especially for GA of CRDs: ObjectMeta must be schema-validated and pruned, like `json.Unmarshal` does this.
This PR adds this in the incoming request serializer and the storage decoder. The former errors when schema validation fails, the later just drops invalid typed fields.
Fixes#59451
```release-note
Meta data of CustomResources is now pruned and schema checked during deserialization of requests and when read from etcd. In the former case, invalid meta data is rejected, in the later it is dropped from the CustomResource objects.

core v1: deprecate the gitRepo volume type
gitRepo stopped accepting new features nearly 2 years ago https://github.com/kubernetes/kubernetes/issues/17676#issuecomment-228650586 and today this behavior can easily be achieved through an init container. The kubelet shelling out to git in the host namespace can also be a security issue on un-trusted repos, as was demonstrated by [CVE-2017-1000117](https://groups.google.com/forum/#!topic/kubernetes-announce/CTLXJ74cu8M). Our own documentation even alludes to this volume type being removed in the future:
> In the future, such volumes may be moved to an even more decoupled model, rather than extending the Kubernetes API for every such use case.
https://kubernetes.io/docs/concepts/storage/volumes/#gitrepo
Closes https://github.com/kubernetes/kubernetes/issues/60999
```release-note-action-required
The GitRepo volume type is deprecated. To provision a container with a git repo, mount an EmptyDir into an InitContainer that clones the repo using git, then mount the EmptyDir into the Pod's container.

rest mappings cannot logically be object converters
A `RESTMapping` in the general sense cannot be a `ObjectConverter` since the conversions are compiled, but the RESTMappings are discovered. This starts isolating the bad assumptions into `kubectl` where they are used and removes the other bad `RESTMapping` use I found in the REST API installer that uses a mapping to determine scopes instead of using the metadata provided during API registration.

code-gen: output golint compliant 'Generated by' comment
New PR instead of reopening #58115 because /reopen did not work.
This won't be ready to merge until the upstream https://github.com/kubernetes/gengo/pull/94 merges. Once that merges, the second commit will be changed to godep-save.sh and update-staging-godeps.sh, and the last commit will be changed to update-all.sh
The failing test is due to the upstream changes not being merged yet

Drop init container annotations during conversion
https://github.com/kubernetes/kubernetes/pull/51816/files#diff-0fa94eafdf1c7cd2171c836b53fd6323 removed special handling of init container annotations in API conversion in 1.8
However, older clients (like 1.7 kubectl) still performed that handling in some paths, which would make an object round-tripped through kubectl show up with additional annotations.
Those additions would get flagged as disallowed mutations in some objects.
This change strips init-container annotations during conversion so that old clients sending init container annotations (which are inert in 1.8+) don't trigger validation errors around immutable fields.
Fixes#54816
```release-note
Restores the ability of older clients to delete and scale jobs with initContainers
```

Support for resource quota on extended resources
**Which issue(s) this PR fixes** :
Fixes#46639#57300 for resource quota support
**Special notes for your reviewer**:
One thing to be determined is if it necessary to Explicitly prohibit defining limits for extended resources in quota, like we did for [hugepages](https://github.com/kubernetes/kubernetes/pull/54292#pullrequestreview-74982771), as the resource is not allowed to overcommit.
**Release note**:

Remove validation failure of Pod priority when the feature is disabled
**What this PR does / why we need it**:
I learned that fields specified in the API should be silently ignored when the feature is disabled. This makes sense as downgrading a cluster would fail otherwise. This PR removes the validation logic that ensures Pod priority is not set when priority feature is disabled.
**Special notes for your reviewer**:
**Release note**:
```release-note
Pod priority can be specified ins PodSpec even when the feature is disabled, but it will be effective only when the feature is enabled.

Add NominatedNodeName field to PodStatus
**What this PR does / why we need it**:
Today, Scheduler uses an annotation called "nominated-node-name" to mark a preemptor Pod. This annotation helps scheduler know about the Pods that are destined to run on the nodes so that the resources made available by preemption is not allocated to a different Pod. In a recent discussion with @bgrant0607, we learned that we should change the annotation to a field as this field can be used by multiple schedulers and other components that may make scheduling-related decisions (descheduler, auto-scaler, kube-arbitrator, ...).

api: validate container phase transitions
https://github.com/kubernetes/kubernetes/issues/54499 exposed an issue where a container was transitioning from the terminal phases of `Succeeded` or `Failed` to `Pending`. It is due to a bug in the kubelet, but additional validation in the API server can prevent this invalid phase transition from being accepted.
@smarterclayton @derekwaynecarr @dashpole @joelsmith @frobware
I confirmed that the reproducer in https://github.com/kubernetes/kubernetes/issues/54499 does not work with this validation in place. The erroneous kubelet status update is rejected:
```
status_manager.go:437] Failed to update status for pod "test_default(2f02ecdf-b92a-11e7-a2d0-1c1b0deeddfa)": Pod "test" is invalid: status.containerStatuses[0].state: Forbidden: may not be transitioned to non-terminated state
```
However, it only works to a point with this particular issue. The termination hangs and eventually the resource is removed from etcd and the status update goes through because there is no old statuses to compare. Not exactly sure how this happens since there is no pod in etcd anymore ¯\\_(ツ)_/¯
