Use MicroMeter to write the Metrics object to influx.

[jgoldverg]

Request:
The current JobMetric.java class represents what we store inside Influx, this gets created from the results that pmeter reports in MetricsCollector.java and then we aggregate the information of all JobMetrics and then finally push the results to influx.
Ideally we convert from manually creating the JobMetric object to instead using MicroMeter Gauges, Counters, and timers.

The ideal implementation would actually use Timed Aspects, to compute times it takes to read and write and then finally compute throughput and other values and report them.
