This metric represents the wall-clock time of the entire pipeline. Unlike per-task timing metrics, it does not cite the Alert Production Metrics confluence page, and it replaces the task tag with pipeline.

This PR registers a metric representing the wall-clock time of the entire pipeline. In practice, it seems to be dominated by scheduling or resource contention; the ratio of total pipeline time to the sum of the individual task times grows with the size of the dataset.
The metric is implemented on lsst/ap_pipe#168.
