Review request for Ambari, Jonathan Hurley, Nate Cole, Robert Nettleton, and 
Sandor Magyari.


Bugs: AMBARI-13551
    https://issues.apache.org/jira/browse/AMBARI-13551


Repository: ambari


Description
-------

When adding components to a Kerberized cluster, the set of hosts to create 
principals for should be limited to only the relevant set.  This is because if 
a component for an existing service is added to an existing host, principals 
and keytab files for the existing components will get unnecessarily updated.
