Review request for Ambari, Jonathan Hurley, Sumit Mohanty, and Sid Wagle.


Bugs: AMBARI-11409
    https://issues.apache.org/jira/browse/AMBARI-11409


Repository: ambari


Description
-------

When upgrading Ambari from 1.7.0 to 2.0.0 to 2.1.0, it fails because in older 
schemas the FK names of columns related to the host_name changed over time.
UpgradeCatalog210 should include the older FK names, and perform a CASCADE 
DELETE on the hosts PK just for good measure.

Testing
-------

Reproduced the issue, and after patching ambari-server.jar was able to get the 
upgrade to get past the Hosts.

Unit Tests for UpgradeCatalog210 passed.


Thanks,

Alejandro Fernandez
