CustomResource with input kind

[geigerzaehler]

Problem description

When creating a k8s.apiextensions.CustomResource with a kind argument that is an input instead of a string pulumi crashes.

Reproducing the issue

import * as pulumi from "@pulumi/pulumi"
import * as k8s from "@pulumi/kubernetes"

new k8s.apiextensions.CustomResource("my-custom-resource", {
  kind: pulumi.output("MyCustomResource"),
  apiVersion: "my-custom-resource/v1",
})

Suggestions for a fix

Looks like the offending code is this

https://github.com/pulumi/pulumi-kubernetes/blob/915998ac39d885684ca90b428a42bba38f0ad7d9/sdk/nodejs/apiextensions/CustomResource.ts#L151

Here kind is expanded to an error message which is obviously an invalid module suffix.

[EronWright]

Looks like the apiVersion and kind were modeled as inputs across all the SDKs, and all suffer from a variation of the problem. Changing the API seems like a last resort here, and so I would advocate for raising an error when the supplied value is not an immediate known value.

One possibility may be to use UnsafeAwaitOutput to wait for the kind to resolve, then throw if the value is unknown. I'm unsure whether that's practical across all the SDKs.

[EronWright]

It is proposed that we do a breaking API change for NodeJS SDK, such that the kind and apiversion properties become eager properties (e.g. string vs Input<string>). Assumedly we'd change the Pulumi schema and mark those properties as plain (ref). It is assumed that no program will break because a non-eager value simply didn't work.
