Need to review all dimensions to see if they are aggregatable metrics

[asirota]

In WARM, there are several endpoint values that are actually metrics but currently defined as connectors. Audit all schema elements, with particular attention to custom fields for Contacts to assign metrics to fields which can be aggregated to make it easier for report designers to quickly make report with common metrics in the raw data. An example is Checked in Count in the Events endpoint.

Details on creating metrics with aggregation by default is described here.
