Review request for Ambari and Nate Cole.


Bugs: AMBARI-6839
    https://issues.apache.org/jira/browse/AMBARI-6839


Repository: ambari


Description
-------

Noticed while doing the DAO work that the Oracle DDL scripts were using 
VARCHAR(4000) in some places where MySQL and PostgreSQL were using TEXT. 
Adjusted the 2 fields that will contain structured JSON data to be CLOB in 
these cases.

On upgrade, we're now using char[].class - The exact implementation of 
org.eclipse.persistence.platform.database.DatabasePlatform will determine the 
actual field type to use (CLOB on Oracle, TEXT on MySQL, etc).
