The grafana image renderer package dependencies need to be documented.                   

 https://issues.opennms.org/browse/NMS-13459?focusedCommentId=63933&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-63933

Description from the original issue:                                                                                                                                                       

On database reports page, creating a report using the 2-panel grafana report throws an error:

Failed to run Jasper report local_Grafana-Dashboard-Report-2ppp

on the web ui. Scheduling the report does not work either.

Have attached the section of the web.log that shows the exception being thrown.

Documentation:

After the second note, in the`/operation/database-reports/database.adoc` file, add the following section to the Database Reports introduction:

Grafana image renderer dependencies
