Review request for Ambari, Dmitro Lisnichenko and Nate Cole.


Bugs: AMBARI-22590
    https://issues.apache.org/jira/browse/AMBARI-22590


Repository: ambari


Description
-------

Written this as 'Blocker' severity, please triage once and decide 

This issue could affect user experience for Patch Upgrades

*Case 1:* Register Patch VDF for Mapreduce service
Try to install the packages
Result: Error for missing Hive service in the VDF (see MR-only.png)

*Case 2:* Add Hive to the patch VDF, os that it now includes both MR and Hive
Try to install the packages
Result: Error for missing Tez service in the VDF (see MR-and-Hive)

This is now confusing as the dependency looks cyclic, we asked to add Hive in 
first case and now asking to add MR again

*Case 3:* Add a new VDF for only Mahout or Oozie. This would prompt for MR due 
to dependency. Now you need to add MR and Hive and then Tez too (see 
Mahout-only.png)

*Expected result:* The message for dependent services should recursively decide 
the services and print them all at once.
