Lightweight query metrics

Query execution metrics used for returning to the client, with precision in the range of microseconds. Differences from QueryProfile: QueryMetrics: A lightweight component designed to provide results to the client in a very short time (within milliseconds). QueryProfile: Provides detailed monitoring data for internal analysis and logging (in milliseconds).

Fields
