Hello,

When trying to use the Grafana module with Icinga Web 2 we get an Uncaught ValueError instead of any visualization when looking at a host problem. In Grafana, we can see graphes but in Icinga we only get the following error message:

```auto
Uncaught ValueError: curl_setopt_array(): Argument #2 ($options) must contain only valid cURL options in /usr/share/icingaweb2/modules/grafana/library/Grafana/ProvidedHook/Grapher.php:220
