I don't really know a lot about the new cata-cores, however under Trinity in 3.3.5 there's a table called `battleground_template`, which is where the data you're looking for is stored.
I've looked at some of the tables for the new Cata-cores and they seem to be set up mostly the same, so you're probably looking for a similarly named table.
Hope it helps!
