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
{code:java}
In PublicAPIsv2 we add the API's which are available in ServiceREST as an API
and the getPolicyByName is not available as an API in ServiceREST.
getPolicyByName ---> (/api/service/{servicename}/policy/{policyname}) in
PublicAPIsv2
I guess we should add the below API in ServiceREST also for the same.
getPolicyByName ---> (/policies/service/{serviceName}/policy/{policyName}) in
ServiceREST
{code}
