Set maximum filesize per container

[stuartcusackie]

I have a problem with users uploaded large image files. For example, a 20mb image stored on a Digital Ocean space takes a while to retrieve and process with glide. Too many of these images can have a massive impact on the server.

You might think that I can just set a POST MAX size on PHP, but unfortunately it's not that simple. I have another asset container that allows large audio files to be uploaded.

So if I could set a maximum file size on each container and prevent large image uploads only then that would be swell. I have warned the users against unnecessarily large image files but they upload them anyway.

Thanks!

Basically #619. You'll want to set a validation rule on the container.
