I don't think we need a dedicated label (i.e. `#renameView`) for this, we
can just re-use `#renameTable` for this. That way you don't have to add any
code to `SparkSqlParser`. The same goes for all these commands.
We can also integrate this with the `ALTER TABLE ...` equivalent rules
(i.e. `ALTER (TABLE|VIEW) ...`. But this is a bit messier, and I'll leave that
to you.
