Review request for Ambari, Jayush Luniya, Mahadev Konar, Robert Nettleton, and 
Yusaku Sako.


Bugs: AMBARI-8867
    https://issues.apache.org/jira/browse/AMBARI-8867


Repository: ambari


Description
-------

When creating a cluster via a blueprint, depending on the services being 
deployed it is possible that the deployment will fail with "Unable to set 
configurations on cluster". This is because we are trying to set set same 
configuration on the cluster multiple times. This was a regression due to 
changes in AMBARI-8561.

This is likely a duplicate of AMBARI-8497 but I haven't tests with that BP yet 
to confirm.

This is a temporary fix specific to this issue.
The larger issue of specifying inter-service configuration dependencies in the 
stack will be addressed separately.

Functional testing of BP associated with Jira.
In the process of running unit tests, will update with results.


Thanks,
