Playground: Plugin Library

[carolynvs]

I'm playing around with making a library for making plugins so that people don't have to implement the boilerplate stuff.

This is the new tiny main function for porter, and it would look the same for a plugin

func main() {
	ctx := context.Background()
	app := porter.New()
	rootCmd := buildRootCommandFrom(app)

	cli.Main(ctx, rootCmd, app)
}

It shoves in all the logic we have for telemetry, context cancellation, panic handling, etc into this new package pkg/cli
