feat: resource type dependencies

Adds a new `TypeDependencies` method to the `Resource` interface that
enables resources to declare a dependency on all resources of a given
type without having to use specific IDs. This is useful for ensuring
that a particular resource is only updated after all resources of a
particular type have been updated, or that a particular resource should
be updated any time a resource of a specific type is updated. This will
be used for a pg_service.conf resource in a subsequent PR.
