mv com/google/domain/registry google/registry

This change renames directories in preparation for the great package
rename. The repository is now in a broken state because the code
itself hasn't been updated. However this should ensure that git
correctly preserves history for each file.

+ * modified by a unit test, and therefore should not be {@code final}.
+ *
+ * <p>When this annotation is used on methods, it means that you should not override the method
+ * and it's only non-{@code final} so it can be mocked.
