Goal: Update the rukpak webhook manifest configurations and ensure any of the webhooks are deployed in a HA manner.

See o/enhancements CONVENTIONS.md for more information.

Open Question:

• Do we need to specify a PodDisruptionBudget resource for the rukpak webhooks?

Misc. Notes:

• We don't need to respect SNO cluster environments for 4.12
• The o/platform-operators repository will be added to the OCP payload

AC:

• Deploy webhooks with two replicas
• Deploy webhooks with a hard pod anti-affinity on hostname
• Deploy webhooks with the maxUnavailable rollout strategy on deployments
