Add PodDisruptionBudget for operator #292

Ensure the service interruption is limited when its pods need to be rescheduled such as:

Draining a node for repair or upgrade.
Accidental deletion of operator deployment.

PodDisruptionBudgets are used to provide detailed information to the kube-scheduler about how many pods in a collection can be available or unavailable at given time. For more info, see the docs at https://kubernetes.io/docs/concepts/workloads/pods/disruptions/#pod-disruption-budgets

[ ] Update worker-operator helm chart
[ ] Include configurable options in the helm chart to enable or disable PDB.

Not required since currently we have a single replica of operator.
