LP1847800 Admin grids support config_field links
For IDL fields which have config_field=true, the value in the admin grid
is rendered as a link to the grid for the linked field. Additionally,
the link contains a gridFilter so the destination grid only displays
rows related to the selected field.
Adds config_field=true values for z39.50 source and two links for hard
due date and hard due date values.
