[CARBONDATA-1232] Datamap implementation for Blocklet
Bypassed btree implementations and used datamap to get the pruned
blocklets. Only driver side datamap is maintained and all required information
will be send to executor.
No datamap/btree will be maintained in executor.
Implementation classes are
org.apache.carbondata.core.indexstore.blockletindex.BlockletTableMap
org.apache.carbondata.core.indexstore.blockletindex.BlockletDataMap
Here only used unsafe storage to store data.
