LUCENE-6085: add back SI.attributes
> Add back SI.attributes (safely)
> -------------------------------
>
> Key: LUCENE-6085
> URL: https://issues.apache.org/jira/browse/LUCENE-6085
> Project: Lucene - Core
> Issue Type: Bug

> We removed this for two reasons:
> * nothing was using it
> * the map is "unsafe" if a codec tried to write to it during in-place dv
> update.
> But Adrien has a real use case (LUCENE-5914), and I think we can just add
> some safety for the updates case (e.g. if the map is unmodifiable then the
> trap will not exist, any put() will throw exception). In general, we should
> have more safety in SI anyway (diagnostics map, too).
