Starting Elasticsearch 7.0, `discovery.zen.hosts_provider` is deprecated in favor of `discovery.seed_providers`. The setting is removed in 8.0, preventing any 8.0 cluster to bootstrap. This commit switches over the Elasticsearch version when building the elasticsearch.yml configuration, to make sure versions lower than 7.0 use `discovery.zen.hosts_provider`, and other versions use the newer `discovery.seed_providers`.
