Support of setting the arangoDB name on the configuration

Hi
I am using spline to capture lineage from Databricks notebooks
I put on the cluseter - on the advanced settings

```
spark.spline.mode ENABLED
spark.spline.lineageDispatcher.http.producer.url http://10.0.19.4:8080/producer
spark.spline.lineageDispatcher http
```

since i have several customers- i dont want to keep the data of all of them on the same arangoDB
so I want a way that the response will be kept on a db per customer.

can we send also the arangoDb name as a parameter so the execution plan lineage data will be kept on a different db
for each cluster i use

thanks in advance
