Review request for Ambari, Myroslav Papirkovskyy and Sid Wagle.


Bugs: AMBARI-5147
    https://issues.apache.org/jira/browse/AMBARI-5147


Repository: ambari


Description
-------

As a part of ambari upgrade, customized log4j properties for HDP services must 
be imported into *-log4j configs(hdfs-log4j, hbase-log4j, etc.). 
Proposals:
1. "ambari-server upgrade" command runs separate java software, which connects 
to the Ambari DB and creates required *-log4j configs. Admin should provide all 
log4j.properties files, for instance, copy them to predefined directory on 
ambari-server node.
