    [SPARK-14691] [SQL] Simplify and Unify Error Generation for Unsupported Alter Table DDL

    #### What changes were proposed in this pull request?
    So far, we are capturing each unsupported Alter Table in separate visit functions. They
should be unified and issue the same ParseException instead.
    This PR is to refactor the existing implementation and make error message consistent for
Alter Table DDL. 
    #### How was this patch tested?
    Updated the existing test cases and also added new test cases to ensure all the unsupported
statements are covered. 

You can merge this pull request into a Git repository by running:

    $ git pull cleanAlterTable
