    [SPARK-16397][SQL][WIP] make CatalogTable more general and less hive specific

    ## What changes were proposed in this pull request?
    
    `CatalogTable` is an internal interface to represent table metadata in Spark SQL, and
should be able to express both hive serde table and data source table. Due to some hive hacks,
data source table only use table properties to store its information, and the `CatalogStorageFormat`
is very hive specific as it's only used by hive serde table currently.
    
    However this is not a good design, the `CatalogTable` is not general enough to express
data source table if we remove hive hacks in the future.
    
    This PR is trying to make `CatalogStorageFormat` general enough to handle all types of
tables in Spark SQL.
    
    ## How was this patch tested?
    
    existing tests.
