Ramachandran updated RANGER-4012:
---------------------------------
Description:
getPolicyByName searches policy by serviceName, policyName simply by traverse
all policies in RangerServicePoliciesCache.
We need to call the DB to fetch policy instead of calling
RangerServicePoliciesCache

However, It takes more time to search for policies from the cache when there
are millions of policies
As well as The above REST API sometimes gives stable data due to the deleted
element is present in the Cache
