Spring-boot: Healthcheck fails with Elasticsearch 2.2.0

[jloisel]

In Elasticsearch 2.2.0, ClusterHealthStatus has been moved to package org.elasticsearch.cluster.health which breaks the health check indicator:

java.lang.ClassNotFoundException: org.elasticsearch.action.admin.cluster.health.ClusterHealthStatus

A simple upgrade should do the trick :+1:

Spring Boot doesn't support Elasticsearch 2.x at the moment. We'll upgrade to 2.x as and when we're using a version of Spring Data Elasticsearch which supports 2.x. In the meantime, the health indicator can be disabled by setting management.health.elasticsearch.enabled=false.
