Andrew Rynhard 8153c2e2a9 feat: add Runtime interface
Instead of passing around a struct, it is better if we pass around an
interface that describes the behavior we want. The Runtime interface
provides a common place to describe runtime specific parameters. This
initial implementation offers the runtime mode, the platform specifics,
and the config.
