Review request for Ambari, Alexander Denissov, bhuvnesh chaudhary, Jayush 
Luniya, Matt, and Tim Thorpe.


Bugs: AMBARI-16665
    https://issues.apache.org/jira/browse/AMBARI-16665


Repository: ambari


Description
-------

With the current implementation, service advisors for the same service are 
loaded multiple times in the stack advisor.

The service advisors should be cached when the stack advisor is loaded and used 
where necessary.


Diffs (updated)
