refactor(metrics): drop metric/status log export (#677)

* refactor(metrics): drop metric/status log export

The status log written to stdout is no longer consumed downstream. The
statusTrack() call is kept because flushMetrics() also resets the metric
accumulators, the CPU usage baseline and the incoming request stats.

* Release 6.51.1-beta

* Update version to 6.51.1
