Container surrogate for UseEmulator for Azure Storage.

[mitchdenny]

Container surrogate for Azure Storage. The idea is that with this optional callback you can manipuate the underlying resource as if it were a container when using the emulator. This was a model proposed at the App Model offsite.

The builder in the callback on UseEmulator is for type AzureStorageEmulatorContainerResource which derives from ContainerResource to activate all of those extension methods. The annotations a proxied through to the underlying resource.

Here is an example of using the code to enable persistent storage:

var builder = DistributedApplication.CreateBuilder(args);

var storage = builder.AddAzureStorage("storage").UseEmulator(container =>
{
    container.UsePersistence();
});

var blobs = storage.AddBlobs("blobs");

builder.AddProject<Projects.AzureStorageEndToEnd_ApiService>("api")
       .WithReference(blobs);

builder.Build().Run();

Very nice

All public APIs should have triple slash comments. We should not merge any PRs without them, perhaps we can fail the build or something if they're missing? //cc @davidfowl and @mitchdenny

[davidfowl]

Yes, we should start to do that.

I've opened #2191 for this.
