The tooling we wrote in DM-25507 only sent on the abstract filter in the filter_name metadata field. SQuaSH treats this field as special and assigns the value in that field to the filter tag which is used by dashboards to filter results. Existing dashboards assume that tag has the name of the physical filter. In order to be consistent with that assumption, change the value assigned to the filter_name field to be the best guess at the physical filter. It's useful to still send on the abstract filter name since it doesn't cost much.
