Spike: Add metrics definition for geo_node_usage

Add YAML metric definitions for geo node usage

This definitions are missing from YAML files we should add the files with the related information

Full key path usage_activity_by_stage.enablement.geo_node_usage

We could have one single file for the root key usage_activity_by_stage.enablement.geo_node_usage with a related JSON schema for the array objects inside

Or we could have one YAML file for each individual metric

Questions/Notes

• All metrics inside are owned by geo group?
• All metrics belong to same product category?
• All metrics have same time frame?
• all metrics will have same instrumentation class(the instrumentation class might have a shared data or context)

If there are difference in metrics we should probably have individual YAML files
