Package v1alpha1 contains definition of the `v1alpha1` configuration document.

Even though the machine configuration in Talos Linux is multi-document, at the moment
this configuration document contains most of the configuration options.

It is expected that new configuration options will be added as new documents, and existing ones
migrated to their own documents.
