    [CARBONDATA-734] Support the syntax of 'STORED BY PARQUET/ORC'

    When I create parquet table with the command below:
    ```shell
    import org.apache.spark.sql.SparkSession 
    import org.apache.spark.sql.CarbonSession._
    val carbon = SparkSession.builder().config(sc.getConf).getOrCreateCarbonSession("hdfs://100.0.0.4:9000/user/hive/warehouse/carbon.store")
    carbon.sql("create table src(key int, value string) stored as parquet")
    ```
    
    It will failed with the error info below:
    ```shell
    java.lang.RuntimeException: [1.1] failure: identifier matching regex (?i)ALTER expected
    
    create table src(key int, value string) stored as parquet
    ^

      at org.apache.spark.sql.SparkSession.sql(SparkSession.scala:592)
      ... 50 elided
    ```
    
    The reason is if we use `STORED AS`, the value of `value.storageHandler().STRING()` will
be null, so if we still invoke `STRING()`, it will be throw exception.
