Top-level keys

Ferry reads three top-level keys of render.yaml and ignores the others with a warning.

Key	On Ferry
`services`	Supported.
`databases`	Supported (Postgres).
`envVarGroups`	Supported.
`projects` / `environments`	Ferry makes them flat. It applies the resources of each environment to this server, with a warning.
All other keys (`previews`, …)	Ferry ignores them, with a warning.
