Wrap HumanReadablePrinter in tab output unless explicitly asked not to
`kubectl get` was not properly aligning its output due to #40848
Fixes an accidental regression. In general, we should not accept an incoming tabwriter and instead manage at a higher level. Fix the bug and add a comment re: future refactoring.
Get command now uses metadata x-kubernetes-print-columns, if present, in Openapi schema
to format output for a resource. This functionality is guarded by a boolean
flag 'use-openapi-print-columns'.

move labels to components which own the APIs
During the apimachinery split in 1.6, we accidentally moved several label APIs into apimachinery. They don't belong there, since the individual APIs are not general machinery concerns, but instead are the concern of particular components: most commonly the kubelet. This pull moves the labels into their owning components and out of API machinery.
@kubernetes/sig-api-machinery-misc @kubernetes/api-reviewers @kubernetes/api-approvers
@derekwaynecarr since most of these are related to the kubelet

Denote if a printer is generic.
This fixes#38779.
This allows us to avoid case in which printers.GetStandardPrinter
returns nil for both printer and err removing any potential panics that
may arise throughout kubectl commands.
Please see #38779 and #38112 for complete context.

Add a server side Get operation
Implement proposal kubernetes/community#363
```release-note
The Kubernetes API supports retrieving tabular output for API resources via a new mime-type `application/json;as=Table;v=v1alpha1;g=meta.k8s.io`. The returned object (if the server supports it) will be of type `meta.k8s.io/v1alpha1` with `Table`, and contain column and row information related to the resource. Each row will contain information about the resource - by default it will be the object metadata, but callers can add the `?includeObject=Object` query parameter and receive the full object. In the future kubectl will use this to retrieve the results of `kubectl get`.

Add comment explaining adding handlers to printers.HumanReadablePrinter
also remove an unnecessary conversion of printers.HumanReadablePrinter
to printers.ResourcePrinter.
