Creation of DataNodeBuilder with module name prefix is very slow

- Created a new hazelcast distributed cache for anchor data config use cases.
- Module name prefix is added for root data node only.
- Cached module name prefix by anchor name on demand from database at
  first call.
- Introduced a new cache holder to have module name prefix of diff.
  levels.
