ConfigFile V2 (Component)

[EronWright]

Proposed changes

This PR implements a new ConfigFile resource (v2) as a Pulumi multi-language component (MLC). The new resource is offered side-by-side with the existing (v1) resource; it is not a drop-in replacement at this time.

Some notable differences with respect to the previous (overlay) implementations:

1. Implemented as an MLC to have a consistent implementation across SDKs and to extend support for YAML and Java.
2. The component name is used as a prefix for the child resource names. Use the resourcePrefix property to override. Note that the resourcePrefix is not applied to the Kubernetes object names.
3. Transformations aren't supported (yet). Support for Pulumi-style transformation is being tracked here, and Kubernetes-style transformation may come in future.
4. The file property is required and the file must exist.

Examples

Here's some usage examples.

YAML

name: issue-2785
runtime: yaml
description: A minimal Kubernetes Pulumi YAML program
resources:
  cf:
    type: kubernetes:yaml/v2:ConfigFile
    properties:
      file: ./manifest.yaml

NodeJS

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

const configFile = new kubernetes.yaml.v2.ConfigFile("my-config-file", {
    file: "./manifest.yaml"
});

const cm = configFile.resources[0].apply(r => r as kubernetes.core.v1.ConfigMap);
export const configmap = pulumi.interpolate`${cm.metadata.namespace}/${cm.metadata.name}`;

Testing

1. New tests of ConfigFile were added to the test suite for the "yaml/v2" package.
