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).

Populate NodeAffinity on top of labels for cloud based PersistentVolumes
**What this PR does / why we need it**:
This PR populates the NodeAffinity field (on top of the existing labels) for PVs backed by cloud providers like EC2 EBS and GCE PD.
**Special notes for your reviewer**:

Updates dynamic Kubelet config to use a structured status, rather than a
node condition. This makes the status machine-readable, and thus more
useful for config orchestration.
Fixes: #56896
This makes the Kubelet config key in the ConfigMap an explicit part of
the API, so we can stop using magic key names.
As part of this change, we are retiring ConfigMapRef for ConfigMap.

Resources prefixed with *kubernetes.io/ should remain unscheduled if they are not exposed on the node.
Currently, resources prefixed with `*kubernetes.io/` get scheduled to any
node whether it's exposing that resource or not.
On the other hand, resources prefixed with `someother.domain/` don't get
scheduled to a node until that node is exposing that resource (or if the
resource is ignored because of scheduler extender).
This commit brings the behavior of `*kubernetes.io/` prefixed resources in
line with other extended resources and they will remain unscheduled
until some node exposes these resources.
Fixes#50658
```release-note
Pods requesting resources prefixed with `*kubernetes.io` will remain unscheduled if there are no nodes exposing that resource.

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
```devel-release-note
Go code generated by the code generators will now have a comment which allows them to be easily identified by golint
```
