Log message:
Update databases/elasticsearch to 5.2.2.

5.2.2

- The request circuit breaker, which track the size of in-flight
  requests, was not decrementing its counter when the connection was
  closed by the client before the response could be returned. This could
  result in no further requests being accepted until the node has been
  restarted. All users should upgrade to take advantage of this bug fix.
- The cgroup functionality (for reading OS stats for containers) had a
  bug in the regex for parsing /proc/self/cgroup which prevented nodes
  with multiple hierarchies from starting up.
- Requests which have been delayed by a shard lock might be executed
  later on a different thread which lacks the request context, resulting
  in the requests being incorrectly rejected as unauthorised.
- Removal of an undocumented syntax for include/exclude parameters in
  the terms aggregation broke certain aggregations in Kibana.

5.2.1

- When stored fields are configured with best_compression, we rely on
  JVM garbage collection to reclaim Deflater/Inflater instances. However
  these classes use little JVM memory but may use significant native
  memory, so if may happen that the OS runs out of native memory before
  the JVM collects these unreachable Deflater/Inflater instances.
- Certain queries can hold a reference to the IndexReader that was used
  to build them. When these queries are cached, this reference causes
  Lucene to hold onto segments long after they should have been deleted.

Log message:
Update databases/elasticsearch to 5.0.0.

* Now requires JDK 8.0.
* Use a different installation layout as some location are now impossible to
  change without patching the Java sources.

=== Breaking changes in 5.0 ===

Migration Plugin
- The elasticsearch-migration plugin (compatible with Elasticsearch 2.3.0
  and above) will help you to find issues that need to be addressed when
  upgrading to Elasticsearch 5.0.

Indices created before 5.0
- Elasticsearch 5.0 can read indices created in version 2.0 or above. An
  Elasticsearch 5.0 node will not start in the presence of indices created
  in a version of Elasticsearch before 2.0.
- Indices created in Elasticsearch 1.x or before will need to be reindexed
  with Elasticsearch 2.x in order to be readable by Elasticsearch 5.x. It is
  not sufficient to use the upgrade API.
