Do not enable Ram/Disk Filter with filter_scheduler
Do not enable Ram/Disk Filter with filter_scheduler

Core/Ram/Disk Filters are not required when using filter_scheduler.

After https://review.openstack.org/#/c/565841 when using these
Filters nova is not scheduling to the ironic nodes and overcloud
deployment fails.
For now just testing the undercloud, good to see what scheduler/filters
are being enabled in overcloud and reflect there as well.
