    [CARBONDATA-782]support unsorted table (when SORT_COLUMNS is empty)

    When SORT_COLUMNS of a table is empty or the table doesn't have dimensions(besides complex
type column),  this table is a unsorted table.
    
    1. Support unsorted table creation.
    e.g. tblproperties('sort_columns'='')  sort_columns is empty, this table will be unsorted
table.
    
    2. During data loading, unsorted table skip sort step.
    
    3. Support query(filter and non-filter) on unsorted table.
    
    4. Use SORT_COLUMNS to create index's KeyGenerator instead of all dimensions.
