> The startup options for the Prometheus Exporter are pretty sparse compared to 
> what the Solr start script offers.
> I've added some options that mirror what Solr offers, such as
>  * SOLR_HEAP
>  * SOLR_JAVA_MEM
>  * GC_TUNE
> Having just the memory settings available would let us start the prometheus 
> exporter with more than 500 Mb of heap, which right now isn't possible as the 
> max heap isĀ [hard coded 
> here|https://github.com/apache/lucene-solr/blob/master/solr/contrib/prometheus-exporter/bin/solr-exporter#L107].
