[ Merge of http://go/wvgerrit/137811 ] Renamed TimerMetric to Timer. Timer is used to generate durations included in metrics, but is not a metric itself. The method of getting the current time did not require creating an instance of std::steady_clock. Updated Distribution and Timer to use default initializers instead of constructor initialization list. Bug: 204946540 Test: Metric unit tests Change-Id: I7ed291b586347dd0b7ab305960883bec04637315
