Bugs: RANGER-3857
    https://issues.apache.org/jira/browse/RANGER-3857


Repository: ranger


Description
-------

It was observed during ranger upgrades that the java patch J10055 taking 
several hours while trying to update the Solr service def to the db. 
This happens only when a solr service is having lot of policies.
Therefore, persisting the updates immediately using transaction manager to 
boost performance.
