Thoughts on improving visibility to SettableGauge

[dennyac]

Been a dropwizard/metrics user since 2015, but just recently came across SettableGauge. Some thoughts on improving visibility usage

• Add more documentation
• Add a getter metricRegistry.settableGauge ( Currently I have to cast Gauge to SettableGauge to be able to set a value)
• Add a default implementation for setValue to the Gauge interface that doesn't do anything to make it backwards compatible with Gauge implementations outside the dropwizard repository (May not be ideal ? Defeats purpose of SettableGauge interface?)

Happy to work on this if people find it useful
