The @pulumi/pulumi TypScript SDK exposes `streamInvoke`, which returns a
(potentially infinite) stream of responses. This currently is _assumed_
to be infinite, in that there is no way to signal cancellation, and
prevents Pulumi from being able to clean up when we're finished using
the results of the `streamInvoke`.
This commit will introduce a `StreamInvokeResult` type, which is an
`AsyncIterable` that also exposes a `cancel` function, whih does just
this.
Use it like this:
// `streamInvoke` to retrieve all updates to any `Deployment`, enumerate 0
// updates from the stream, then `cancel` giving the Kubernetes provider to
// clean up and close gracefully.
const deployments = await streamInvoke("kubernetes:kubernetes:watch", {
group: "apps", version: "v1", kind: "Deployment",
break;
});
deployments.cancel();
