Restart the Cribl server

Restart the Cribl server.<br/><br/>This operation requires <code>system.restart</code> to be set to <code>api</code> in <code>cribl.yml</code>. If this setting is not configured, the request returns a <code>403</code> error.<br/><br/>Restarting the server causes a brief period of downtime while the process stops and restarts. All in-flight events are drained before the process exits. Use <code>POST /system/settings/reload</code> to apply configuration changes without a full restart.
