Introduces support for leader election between multiple replicas of the Operator pod.
Now we pass the name of the pod to each operator pod and start with
2 replicasby default, using kubernetes lock leases it then elects a leader, which then patches the pod so that now the operator service only hits that pod (the leader)We have the requirement to have a single pod serve as the operator API due to the fact that when we are doing online update, the MinIO pods will attempt to download their binary from the operator pod via the operator service, so a single pod should host the downloaded file.
