- Addition of storage of extra counters for Grafana
JIRA: YARDSTICK-1036
This stores a number of extra counters in influxdb for Prox test cases.
It also stores existing counters with a "succcess_" tag.
Previously throughput where stored without success or failure indication.
Also "Result_" counters are also stored.
These can now be used by Grafana to graph output.
