Generates CDK CLI configurations from the source of truth in packages/aws-cdk/lib/config.ts. Currently generates the following files:

• packages/aws-cdk/lib/parse-command-line-arguments.ts: yargs config.
• packages/aws-cdk/lib/user-input.ts: strongly typed UserInput interface.
• packages/aws-cdk/lib/convert-to-user-inpu.ts: converts input from the CLI or cdk.json into UserInput.

import { renderYargs } from '@aws-cdk/user-input-gen';

declare const config: CliConfig;

fs.writeFileSync('./lib/parse-command-line-arguments.ts', await renderYargs(config));

This package exports renderYargs(), which accepts the CLI command config as input and returns the yargs definition for it as a string.

Some values must be computed at runtime, when a command is run. This is achieved with dynamic values; if the framework sees a CLI option with a dynamicValue, then the framework will reference the corresponding parameter. We should automatically generate the parameter definitions, instead of manually adding them, in the future.
