LGTM overall +1.
One question: since we now cast `ROWTIME` / `PROCTIME` directly to `LONG`,
I wonder, do we want to revisit the decision that creates dedicated types for
`ROWTIME` / `PROCTIME`?
> Support to define an existing field as the rowtime field for TableSource

> Currently {{DefinedRowtimeAttribute}} can define an appended rowtime field
> for a {{TableSource}}. But it would be helpful if we can support to define an
> existing field as the rowtime field. Just like registering a DataStream, the
> rowtime field can be appended but also can replace an existing field.
