   ### Description of PR
   https://issues.apache.org/jira/browse/HDFS-16459
   Router' RBFMetrics was not register  in MetricsSystem. We can't find these metrics from PrometheusSink. Maybe we should fix it. 
   
    
   
   After fix it ,  some  RBFMetrics will export like this 
   ```
   # HELP rbf_metrics_current_tokens_count Number of router's current tokens
   # TYPE rbf_metrics_current_tokens_count gauge
   rbf_metrics_current_tokens_count{processname="Router",context="dfs",hostname="xxxx"} 2 
   ```
   
   ### How was this patch tested?
   no new test
   
   ### For code changes:
   1. DefaultMetricsSystem.instance().register 
   2. use `@Metric` to export metrics
