Are you absolutely certain that there is a setting for zkClientTimeout
that is actually getting applied?  The default value in Solr's example
configs is 30 seconds, but the internal default in the code (when no
configuration is found) is still 15.  I have confirmed this in the code.

Looks like SolrCloud doesn't log the values it's using for things like
zkClientTimeout.  I think it should.
