Metrics: Add custom witness for plugins, and code clean up

Remove LongGauge and DoubleGauge and Replace with NumberGauge
 - This is an unecessary distiction for Gauges and can complicate the serialization. Double/Float should serialize with decimal precision, and Jackson handles this by default.

Add custom witness to match existing Ruby API, such that existing Ruby plugins should not need changes

Remove namespace from LazyDelegatingGauge
 - It was only there for logging, but newer versions (not here) will completely remove the concept of namespace.
