Support container images!

Now here's something that'll let us avoid the fpco/stack-build:lts-13.30 stuff, by using our own executables based on a smaller docker image.

That's nice, makes some cleanup possible. We'll likely need serverless to support this first though.

I think there's an option where you upload it to ecs via aws-cli and then you specify without specifying the runtime or function name, and it runs the docker ENTRYPOINT.

This seems to be it: serverless/serverless#8572. However, it expects the user to manage the ECS image themselves - if you just define a function it should, for example, leave no traces in your account after it's deleted. I hope some support for building the images is added to Serverless itself, then we can use that.

Wait, isn't the first code block in this article demonstrating how to do the automatic building? https://www.serverless.com/blog/container-support-for-lambda

Well yes, turns out that they do build now. https://github.com/serverless/serverless/blob/master/CHANGELOG.md#2200-2021-01-21 So I don't think this is blocked anymore.
