Recognize ObsCore, Recognize UCD, do normal catalog overlay.
The ticket is just 1.1 of DM-15783 but lays the foundation for more. Using upload, when a table is sent to the client. If it is a VO like table, determine if it is ObsCore or if there is ra/dec information based on UCD and do the normal catalog overlay.
The source of the table does not have to be a VO table we just want to be able to recognize VO type meta-data.
