Title: Plugin crashes Vagrant if nothing is configured

It seems that Vagrant does not call `finalize!` for the configuration object if there is no configuration for it in the Vagrantfile.

This seems like bug or unfortunate feature in Vagrant, bu we should anyway be prepared that the configuration keys can be left in `UNSET_VALUE`. A good idea might be to call `finalize ourself.
