Fail safely if elasticsearch is down or unconfigured
* If elasticsearch server is down, or the configuration variables are not provided at startup or in a configuration file, then do not allow the system to simply crash, but instead, inform the user that they cannot use the services that depend on elasticsearch to be running.
