Performance Indicator Metrics guide

This guide describes how to use metrics definitions to define performance indicator metrics.

To use a metric definition to manage a performance indicator:

1. Create a merge request that includes related changes.
2. Use labels ~"product intelligence", "~Data Warehouse::Impact Check".
3. Update the metric definition performance_indicator_type field.
4. Create an issue in GitLab Product Data Insights project with the PI Chart Help template to have the new metric visualized.
