Allow Setting of Defender PriorityClass

When spinning up clusters with a large number applications, the servers sometimes hit resource limits and not allow the defender daemonsets to be pushed to a node. This causes the defender pods to get stuck in a 'Pending' statue until you manually evict some pods from the associated node. It looks like the daemonset call allows setting of priorityClass for the defender daemonset which would solve the issue by allowing eviction of other pods.
