Review request for ranger, madhan, Madhan Neethiraj, and Ramesh Mani.


Bugs: RANGER-2665
    https://issues.apache.org/jira/browse/RANGER-2665


Repository: ranger


Description
-------

When policy-deltas are enabled, and the only change is to a zone policy, then 
the policy-engine used for delegate-admin processing fails to build. This may 
lead to incorrect processing of delegate-admin privileges when the affected 
policy has delegate-admin policy-item(s).

Encapsulated logic for determining if a given ServicePolicies object contains 
policy-deltas, and used it to decide if a new policy engine needs to be built 
from scratch or from existing policy-engine using deltas provided in 
ServicePolicies object.

Testing

Passes all unit tests. Tested with cluster configured with ranger-admin enabled 
for using policy-deltas.


Thanks,
