Module swanling::metrics

Optional metrics collected and aggregated during load tests.

By default, Swanling collects a large number of metrics while performing a load test. When SwanlingAttack::execute() completes it returns a SwanlingMetrics object.

When the SwanlingMetrics object is viewed with std::fmt::Display, the contained SwanlingTaskMetrics, SwanlingRequestMetrics, and SwanlingErrorMetrics are displayed in tables.
