Please see at the to of this section:
"The following is a list of options for configuring application settings
for the Data Warehouse service. These options are available in the
/usr/share/ovirt-engine-dwh/services/ovirt-engine-dwhd/ovirt-engine-dwhd.conf
 file. *Configure any changes to the default values in an override file
under /etc/ovirt-engine-dwh/ovirt-engine-dwhd.conf.d/. Restart the Data
Warehouse service after saving the changes."*

So you need to add a file under
*/etc/ovirt-engine-dwh/ovirt-engine-dwhd.conf.d/*
The file name is not important. It should end with ".conf"
