Add leader elections flags/values to the deployment manifests (#455)
Issue: aws-controllers-k8s/community#1753 (comment) ACK controllers use k8s-sigs/controller-runtime behind the scenes, which support leader election. This feature is not properly working due to a missing configuration `LeaderElectionNamespace` which is used by the manager to create `k8s.io/coordination` Lease objects. This patch sets the default `LeaderElectionNamespace` to `ack-system` and adds the capability of enabling leader election using helm values.
