Major Description
Currently, every change to any tag/service-resource/service-resource->tag mapping causes complete rebuilding of portions of policy-engine that map accessed resource to their tags. There are several disadvantages:
1. Compute time for rebuilding
2. Large traffic from ranger-admin to each of the plugins
3. Large load on JVM memory system because of frequent complete rebuilding of portions of policy-engine.
It will be more optimal to communicate only the changes to tags and apply them to existing policy-engine.
