[infinispan-issues] [JBoss JIRA] (ISPN-7742) Update Elasticsearch integration tests to use version 5.3 (from 2.x)

Update Elasticsearch integration tests to use version 5.3 (from 2.x) -------------------------------------------------------------------- Key: ISPN-7742 URL: https://issues.jboss.org/browse/ISPN-7742 Project: Infinispan Issue Type: Task Components: Build process, Test Suite - Query Reporter: Sanne Grinovero Assignee: Sanne Grinovero Fix For: 9.1.0.Final, 9.1.0.Alpha1 Hibernate Search now supports both Elasticsearch versions {{2.x}} and {{5.x}}. I'll update the Infinispan integration tests to target the improved version 5.x, not least the configuration and integration tests are slightly simpler to maintain as we no longer need additional plugins. Also, we'll eventually drop support for the older Elasticsearch version.
