Supported number of kafka-lag-exporter replicas?

[amccague]

Hi is there a documented reason that the number of replicas in the helm-chart is hard coded to 1?

Furthermore, if multiple replicas are not supported then would it be prudent to set the deployment strategy to be Recreate or even make it a Statefulset to ensure only a single replica exists? This could potentially have other benefits such as being able to set a static group.consumer.id
