Review request for ranger, Madhan Neethiraj, Mahesh Bandal, Ramesh Mani, 
Sailaja Polavarapu, and Velmurugan Periasamy.


Changes
-------

Ensure that policyVersion is set correctly in the default service policies.


Bugs: RANGER-3291
    https://issues.apache.org/jira/browse/RANGER-3291


Repository: ranger


Description
-------

This issue is seen only if incremental policy downloads are enabled. If the 
first ever policy download request made by the service returns no policies or 
policy-deltas (because ranger repository does not contain any policies), then 
the policy-engine's value remains null. This causes any subsequent incremental 
downloads to fail with NPE.

The fix is if the policy-engine does not require any update after policy 
download, then ensure that it is initialized with default-service-policies.
