Substitute availability zone example with a better one about examples

Are we sure we want to do this? After fixing pulumi/pulumi#331, the example will be rather simple, and show off many nice aspects of the platform.

It'll just be

import * as aws from "@pulumi/aws";
import * as webserver from "./webserver"; // use the new custom component
for (let zone of aws.getAvailabilityZones().names) {
    let server = webserver.createInstance(`web-server-www-${i}`, "t2.micro", zone);
}

Totally agreed - if/when we address pulumi/pulumi#331, I'd love to have this example.

It's just a shame to have one of of earliest examples highlight the current ugliness of our system here so prominently right now for potential customers we are sharing this with right now.

If we feel confident we'll have addressed pulumi/pulumi#331 in the near term, then we can leave this as is.

I propose we focus on just finishing the underlying work item here, and save the busywork of churning our examples. We can't ship without #331, and it's destabilizing enough that we can't afford for it to go beyond M10.

Works for me. Closing this one out for now. @lindydonna Feel free to reopen if you feel differently.

I love how simple the example will be! Agree with keeping it for now.
