use micrometer metrics

[pjfanning]

I have worked on a fork of metrics-sql as a proof-of-concept that uses micrometer instead of dropwizard metrics. The advantage for me is that micrometer can be used as an abstraction for any underlying metrics framework.

I can continue with my fork as a standalone project but if you think it's a good idea, maybe it can be merged into your project instead (after my tests are beefed up, etc).
