Code Issues Proposed changes

Enable Request Filter for Image Types 

This change enables `scheduler/query_placement_for_image_type_support`
by default for all deployments. Setting it causes the scheduler to ask
placement only for compute hosts that support the disk_format of the
image used in the request which is beneficial for example, the libvirt
driver, when using ceph as an ephemeral backend, does not support ``qcow2``
images (without an expensive conversion step).
