The list of nodes to be queried for configuring OSDs
should include all of the K8s nodes before the placement
or other filters are applied. The operator was sometimes
missing configuring OSDs on nodes if the discover pod
hadn't finished running on a node. Now the osd prepare
job will be triggered on a node even if the discover pod
hasn't yet run there.
