refactor: split config.Provider into Config & Container
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.
