Ensure PodDisruptionBudgetAtLimit alert is silenced

[machadovilaca]

What this PR does / why we need it:

The Pod Disruption Budget (PDB) prevents pod disruptions for migratable virtual machine images. If the PDB detects pod disruption, then openshift-monitoring sends a PodDisruptionBudgetAtLimit alert every 60 minutes, for every namespace, which includes virtual machine images that use the LiveMigrate eviction strategy. This is causing noise for all OpenShift Virtualization operator users.
