https://github.com/apache/lucene-solr/pull/98
distributed expand=true&fl=key NPE fix, expand=true&distrib.singlePass=true
consideration
https://issues.apache.org/jira/i#browse/SOLR-6604
scenario:
* select?expand=true&fl=key hit NPE in ExpandComponent.handleResponse when
the responses of the EXECUTE_QUERY contained no expanded element despite the
requests' purpose including PURPOSE_GET_FIELDS
* select?expand=true&distrib.singlePass=true worked but relied on other
preceding components triggering a GET_FIELDS stage
changes:
* add TestExpandComponent and DistributedExpandComponentTest test cases
* change code to fix NPE
* change code to avoid distrib.singlePass reliance on other components
* tweak test cases to randomly alternate between docValues=false and
docValues=true collapse fields
