> While creating a Carbondata table from dataframe, currently it is not possible to specify
columns that needs to be included in or excluded from the dictionary. An option is required
to specify it as below : 
> df.write.format("carbondata")
>   .option("tableName", "test")
>   .option("compress","true")
>   .option("dictionary_include","incol1,intcol2")
>   .option("dictionary_exclude","stringcol1,stringcol2")
>   .mode(SaveMode.Overwrite)
> .save()
> We have lot of integer columns that are dimensions, dataframe.save is used to quickly
create tables instead of writing ddls, and it would be nice to have this feature to execute
POCs.
