Chris Friesen 2fe96819c2 Remove ram/disk sched filters from default list
Since we now use placement to verify basic CPU/RAM/disk resources,
we should default to disabling the equivalent scheduler filters.

Oddly enough, CoreFilter was already disabled so now also disable
RamFilter and DiskFilter.

Since we now use Placement to verify basic CPU/RAM/disk resources when
using the FilterScheduler, the ``RamFilter`` and ``DiskFilter`` entries are
being removed from the default value for the ``enabled_filters`` config
option in the ``[filter_scheduler]`` group. If you are overriding this
option, you probably should remove them from your version. If you are
using CachingScheduler you may wish to enable these filters as we will
not use Placement in that case.
