Description: The current UDTF leverages the table.join(expression)
interface, which is not a proper interface in terms of semantics. We would like
to refactor this to let UDTF use table.join(table) interface. Very briefly,
UDTF's apply method will return a Table Type, so Join(UDTF('a, 'b, ...) as 'c)
shall be viewed as join(Table) (was: UDTF's apply method returns a Table Type,
so Join(UDTF('a, 'b, ...) as 'c) shall be viewed as join(Table))
