Document the /rest/graphs endpoint

I need to be able to determine what graphs are available for a particular IP or SNMP interface from the REST API.

I am able to get the interfaces but currently the only options I found for determining what graphs were available was to

• make a request for every possible graph and see which do not return a 404
• scrape the html of "/opennms/graph/results.htm?reports=all&resourceId=node[XXX].interfaceSnmp[YYY]" looking for the graph urls and parsing the 'reports' url params

Both of these are far from ideal!

I'm thinking a new endpoint along the lines of

• /opennms/rest/nodes/ {nodeId}

  /ipinterfaces/

  {ipInterface}

  /reports

If this is already possible, sorry I've looked and couldn't find it anywhere.
