Donal McBreen 55ec6ca0a6 Allow accessory only configurations
If there are accessories defined in the configuration, we'll not require
servers to be defined as well.

This allows for accessory-only configurations which allows you to run
external images with kamal-proxy for zero-downtime deployments.

We don't manage image cleanup for accessories though so the user will
need to deal with that themselves.
