Service types

Each service type of Render has an equal type on Ferry.

The type in render.yaml, and the type on Ferry

Render `type`	Ferry
`web`	Web service. With `runtime: static` (or the old `env: static`), a static site.
`pserv`	Private service.
`worker`	Background worker.
`cron`	Cron job.
`static`	Static site.
`redis`, `keyvalue`	A Redis datastore.

Key value stores

For a key value store, Ferry uses only name and plan, and its own keys memoryLimit and cpuLimit.

Ferry ignores each other key, such as ipAllowList or maxmemoryPolicy, with a warning.

Top-level keys

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

Service keys

Most keys of a service have the same meaning on Ferry. Ferry changes some keys and ignores others.
