balena preload fails to build image

[jellybob]

It appears the preload Docker image is not available on Docker hub, at least if I'm reading the source of the balena-preload module correctly. Configuration in the module references the image balena/balena-preload, but the image returns a 404 when looking on Docker Hub.

Expected Behavior

Running balena preload should result in building an image pre-provisioned with our Docker images.

Actual Behavior
