[CARBONDATA-2099] Refactor query scan process to improve readability
Unified concepts in scan process flow:
1.QueryModel contains all parameter for scan, it is created by API in
CarbonTable. (In future, CarbonTable will be the entry point for various table
operations)
2.Use term ColumnChunk to represent one column in one blocklet, and use
ChunkIndex in reader to read specified column chunk
3.Use term ColumnPage to represent one page in one ColumnChunk
4.QueryColumn => ProjectionColumn, indicating it is for projection

[CARBONDATA-1544][Datamap] Datamap FineGrain implementation
Implemented interfaces for FG datamap and integrated to filterscanner to
use the pruned bitset from FG datamap.
FG Query flow as follows.
1.The user can add FG datamap to any table and implement there interfaces.
2. Any filter query which hits the table with datamap will call prune
method of FGdatamap.
3. The prune method of FGDatamap return list FineGrainBlocklet , these
blocklets contain the information of block, blocklet, page and rowids
information as well.
4. The pruned blocklets are internally wriitten to file and returns only
the block , blocklet and filepath information as part of Splits.
5. Based on the splits scanrdd schedule the tasks.
6. In filterscanner we check the datamapwriterpath from split and reNoteads
the bitset if exists. And pass this bitset as input to it.

[CARBONDATA-2080] [S3-Implementation] Propagated hadoopConf from driver to
executor for s3 implementation in cluster mode.
Problem : hadoopconf was not getting propagated from driver to the executor
that's why load was failing to the distributed environment.
Solution: Setting the Hadoop conf in base class CarbonRDD
How to verify this PR :
Execute the load in the cluster mode It should be a success using location
s3.

[CARBONDATA-1543] Supported DataMap chooser and expression for supporting
multiple datamaps in single query
This PR supports 3 features.
1.Load datamaps from the DataMapSchema which are created through DDL.
2.DataMap Chooser: It chooses the datamap out of available datamaps based
on simple logic. Like if there is filter condition on column1 then for
supposing 2 datamaps(1. column1 2. column1+column2) are supporting this column
then we choose the datamap which has fewer columns that is the first datamap.
3.Expression support: Based on the filter expressions we convert them to
the possible DataMap expressions and do apply expression on it.
For example, there are 2 datamaps available on table1
Datamap1 : column1
Datamap2 : column2
Query: select * from table1 where column1 ='a' and column2 =b
For the above query, we create datamap expression as
AndDataMapExpression(Datamap1, DataMap2). So for the above query both the
datamaps are included and the output of them will be applied AND condition to
improve the performance
