> The HDFS metrics based alerts defined in alert_metrics_deviation.py is 
> agnostic of federated Namenodes.
> Tasks:
> When federation is enabled we should add an alert instance per nameservice 
> for the HDFS metric based alerts.
> Currently, we track metrics based alerts for:
> RPC processing latency
> RPC queue latency
> NN Heap usage
> There are multiple alerts based on whether service port is enabled and also 
> different time windows. 
> For every alert type, there should be an instance of the alert per 
> nameservice.
