Review comment:
> SystemConsumerMetrics to take a configurable group name
Alerting in ingraphs and auto-scaling rules at LinkedIn are defined based
upon the samza generated metric names. Group name is prefix and initial part of
the generated metric name. It will be better to factor these use-cases into
account and maintain backwards compatibility when changing the metric names.
