Consider changing metrics to be multi-dimensional

[cskinfill]

The current metrics support in spring boot actuator only allow for a string name and a value. But if we use a metrics database like influxdb or others, its cumbersome to write a transformer that can unravel the metric name into a measurement, tag, field structure. It seems easier to support this mult-dimensional structure when the metric is created, and then provide a way to flatten it for graphite, statsd, etc., then try and go the other way.

Something perhaps like GaugeService.submit(String metric, double value, Map<String, String> tags) and then update Metric to store the tags.

Thoughts?
