Review request for Ambari, Robert Nettleton and Sid Wagle.

Bugs: AMBARI-13129

Repository: ambari


Allow Hive and Atlas to be integrated by Ambari automatically when deploying via a blueprint.
- Introduce a new Atlas client component in the HDP stack which will be used for all Atlas
service integration
- Set/Update the appropriate properties when Hive and Atlas are both included in the cluster

The end result of this work will be seamless integration of Hive and Atlas when deployed via
a blueprint. The user will simply need to include the appropriate Hive and Atlas components
and all configuration/integration is done automatically by Ambari.

This patch doesn't include any component depencency between HIVE and the ATLAS client so if
the user doesn't specify an ATLAS client on the HIVE nodes, then they will need to manually
configure the hive/atlas configurations.  This is because Ambari doesn't directly support
conditional dependencies.  This should be added in another patch so that the ATLAS client
is added as necessary to the blueprint during topology validation.

Functional Testing:
- Deployed clusters via blueprint with different topologies containing both Hive and Atlas.
- In the process of UI test to ensure that addition of ATLAS_CLIENT doesn't cause issues.

Unit Tests:
- Added new unit tests for BP config processor changes
- In the process of running full suite if unit tests

Will update the review with the above in-progress testing prior to merging.
