Do not restart Elasticsearch on config change when restart_config_change is set to false

[SndR85]

This change will fix that Elasticsearch service is not being restarted when restart_config_change is set to false. Without this change Elasticsearch was still restarted on config changes even when restart_config_change was set to false. See also issue #1113

@fatmcgav can we have this PR merged and released soon? I dont like to fork the module again for such a tiny issue.

I think #1111 is what's needed, no need to globally notify entire class

If you use that method then Elasticsearch will never restart after a config change, is it?

Never mind, I see it's notifying the service from each resource in elasticsearch::config only if restart_config_change is set true.
