Review request for Ambari, Robert Levas, Robert Nettleton, Sandor Magyari, Sumit Mohanty,
and Sebastian Toader.

Bugs: AMBARI-14722

Repository: ambari


If the config_recommendation_strategy is 'ONLY_STACK_DEFAULTS_APPLY' in the cluster creation
template, it should apply configurations only on stack defaults. 
In case of a user overrides a stack default property, stack advisor output should not be considered,
and force to use the user provided property.
(ALWAYS_APPLY strategy still won't use user provided properties in the output of stack advisor,
only as inputs)

Diffs (updated)



Testing (updated)

FT: provision with multiple blueprints (with user provided properties in the cluster-creation
tempalte and in the blueprint too)
Unit testing done.
