Unfortunately CQ can't be tested with an embedded server. For Geode, there can be only
one instance of Cache in JVM: server or client. CQ is client / server topology.

<p>This test requires an external Geode instance

<p>Temporary test until we have a proper way to start real geode server

  copy artifact jars from common/target/*.jar into $GEMFIRE_HOME/extensions/
  manually start gfsh
  $ start locator --name=locator1 --port=10334
  $ start server --name=server1 --server-port=40411
  $ create region --name=persons --type=REPLICATE
