CDB-4267 Disable high res gecoding batch api by config 

Just keep it there. If the config is missing it does no harm. Neither if it is set to false (basically we want to be explicit about disabling, don't we?)

It only affects the batch api, that is, if there are less than 1100 rows to gecode after using cache, then the user won't be affected. That should minimize impacts during maintenance windows.

@lbosque or @zenitraM can you please take a look? We'll have to use it today. Thanks!
