Review request for Ambari, Jonathan Hurley and Tim Thorpe.


Bugs: AMBARI-22431
    https://issues.apache.org/jira/browse/AMBARI-22431


Repository: ambari


Description
-------

EU/RU does not create/load default of new config types when the source stack 
and target stack is the same. This JIRA introduces a new config task type for 
creating/loading defaults of a new config type when stack does not change 
during EU/RU. This is particularly important for EU/RU of custom services where 
their stack may not change at all.

Testing
-------

unit tests, patch Ambari 2.6 cluster with the changes, upgrade from HDP 2.6.2 
to 2.6.3, where zookeeper was modified to have zookeeper-fake that needs to be 
created and configured during EU.


Thanks,
