    This PR changes:
    1.  A `Maps` utility is added to provide `getOrDefault` method and avoid JDK 8 dependency
    2. `CarbonLoadModelBuilder` is added to build `CarbonLoadModel`
    3. `DataLoadingUtil.scala` and `ValidateUtil.scala` is changed to java implementation
and moved to `CarbonLoadModelBuilder` in processing module
    After all these changes, carbon-spark dependency can be removed from store-sdk module

    [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-2025] Unify all path construction through CarbonTablePath static method
    Refactory CarbonTablePath:
    1.Remove CarbonStorePath and use CarbonTablePath only.

before using it, thus code is cleaner and GC is less.

    [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-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.
    This closes #1471

    [CARBONDATA-2023][DataLoad] Add size base block allocation in data loading
    Carbondata assign blocks to nodes at the beginning of data loading.
    Previous block allocation strategy is block number based and it will
    suffer skewed data problem if the size of input files differs a lot.
    We introduced a size based block allocation strategy to optimize data
    loading performance in skewed data scenario.
