serialization

-------------------------------
Summary: Call getValue() only once in gauge serialization

Project: Flink
Issue Type: Improvement
Components: Metrics
Affects Versions: 1.4.2
Reporter: Jisu You
Fix For: 1.6.0
MetricDumpSerialization.serializeGauge() calls gauge.getValue twice in gauge serialization. This is troublesome for those who reset gauges in getValue. serializeGauge() should only call getValue once.
