      classes-recipe/core-image: drop debug-tweaks IMAGE_FEATURE

      Remove the 'debug-tweaks' IMAGE_FEATURE. It sounds friendly and kind to
      developers, but it results primarily in an image which root can login
      remotely without a password.  This is incredibly useful for local
      development and testing purposes, but we really want to be explicit that
      this is what is happening instead of hiding it behind a vague "debug
      tweaks" statement.

      To preserve the eixsting behaviour, debug-tweaks should be replaced with
      these features:

        allow-empty-password empty-root-password allow-root-login post-install-logging
