Currently, the UDTF in Table API is used with `crossApply`, but is used
with JOIN in SQL. UDTF is something similar to Table, so it make sense to use
`.join("udtf(c) as (s)")` in Table API too, and join is more familiar to users
than `crossApply`. The `outerApply` should be renamed to `leftOuterJoin`.
