new xslt

[Christopher Gross]

In 3.x Solr (and earlier) I was able to create a new xslt doc in the
conf/xslt directory and immediately start using it.

In my 4.1 setup, I have:
  <queryResponseWriter name="xslt" class="solr.XSLTResponseWriter">
    <int name="xsltCacheLifetimeSeconds">5</int>
  </queryResponseWriter>

But after that small wait I still can't use it.  Is there another setting
that I'm missing somewhere?  I am using SolrCloud, do I need to have
zookeeper push that change out?

Thanks!
