See #7230 This is a step towards preparing for multi-doc config. Split the `config.Provider` interface into parts which have different implementation: * `config.Config` accesses the config itself, it might be implemented by `v1alpha1.Config` for example * `config.Container` will be a set of config documents, which implement validation, encoding, etc. `Version()` method dropped, as it makes little sense and it was almost not used. `Raw()` method renamed to `RawV1Alpha1()` to support legacy direct access to `v1alpha1.Config`, next PR will refactor more to make it return proper type. There will be many more changes coming up. Signed-off-by: Andrey Smirnov <andrey.smirnov@talos-systems.com>
