[ IDEA ] Process metrics write to timeseries database.

Hi Guys,

Just an idea, It's possbile to write metrics to timeseries database. so that we can see the realtime metrics.

`psrecord 1330 --log activity.txt --db influx://localhost:5581`

Start by reviewing the psrecord command and its existing logging options, then determine how the proposed `--db influx://localhost:5581` interface should fit the current CLI. Define the metrics, connection behavior, and tests needed before implementing InfluxDB output; done means realtime process metrics can be written through the documented command.
