[Hawkular-dev] Ability to group by datapoint tag in Grafana

[Gareth Healy]

@John S,
>From looking at the JIRA, i've tried calling /stats and /data (*deprecated*)
but don't get back data i'd want.

If i search via tags; i get all empty buckets (both metric and datapoint
tags). If i search via metricNames; i get back buckets but since its
aggregated i am back to the original problem.

Am i querying via tags incorrectly? cURL commands i've been using:

   - get buckets - https://gist.github.com/gareth

@Joel,
I'd not done the other endpoints as i wanted to prove it first, and then if
accepted, complete the rest.

Your point about insertion; I'll let others comment who know the metrics
codebase better than myself.

Cheers.
