     [CARBONDATA-2532][Integration] Carbon to support spark 2.3 version

    ```
    ## What changes were proposed in this pull request?
    In this PR inorder to hide the compatibility issues of columnar vector API's from the existing common classes, i introduced an interface of the proxy vector readers, this
    proxy vector readers will take care the compatibility issues with respect to spark different versions.
    Column vector and Columnar Batch interface compatibility issues has been addressed in this PR, The changes were related to below modifications done in spark interface.
   
    Highlights:
    a) This is a refactoring of ColumnVector hierarchy and related classes.
    b) make ColumnVector read-only
    c) introduce WritableColumnVector with write interface
    d) remove ReadOnlyColumnVector
    e) Fixed spark-carbon integration API compatibility issues - By Sandi
    f) Corrected the testcases based on spark 2.3.0 behaviour change
    g)  Excluded following dependency from pom.xml files <groupId>net.jpountz</groupId><artifactId>lz4</artifactId> as spark 2.3.0 changed
          it to org.lz4, so removed from the test class path of spark2,spark-common-test,spark2-examples
    ## How was this patch tested?
    Manual testing, and existing test-case execution
    ```
