Review request for Ambari, Vivek Ratnavel Subramanian and Yusaku Sako.


Bugs: AMBARI-21640
    https://issues.apache.org/jira/browse/AMBARI-21640


Repository: ambari


Description
-------

List of dashboards affected.
HDFS-Users
HBase - Tables
HBase - Users
Kafka - Topics
Nifi - Hosts


The problem here is that the 'cluster name' field added through AMBARI-20896 
was not handled correctly. Whenever the Cluster name is not present, it appends 
an 'undefined' to the GET metrics URL causing wrong requests.
