Draft: Set replicaAutoBalance to "best-efforts" to enable balancing longhorn replicas
What does this MR do and why
This MR enables the balancing of longhorn replicas automatically across the nodes.
By default, no replica auto-balance will be done.
Setting replicaAutoBallance
to best-effort
to avoid the risk to end up with all the replicas on the same node after a rolling upgrade.
