> In the CLI, if a user inputs an incorrect column name, we currently just print the bad column name in the query.  Typically, the user needs to "describe" the table to figure out the correct column.
> This patch prints out a list of valid column and partition names in the table when a user inputs an incorrect column name.
> e.g., 
> {{Error in semantic analysis: Invalid table alias or column reference 'col_does_not_exist' (possible column names are: col1, col2)}}
