Review Comment:
Here both exists the `LogicRefreshMode` and `RefreshMode`, the
`LogicRefreshMode` is logical concept and the `RefreshMode` represents the
physical refresh mode, corresponding to a streaming or batch flink job. If we
don't specify the `REFRESH_MODE` when create materialized table. The
`LogicalRefreshMode` value is `AUTOMATIC`, then we will derive the
`RefreshMode` via freshness. We allow user to specify the `REFRESH_MODE` when
create materialized table, the starting point of the design is to consider that
the `RefreshMode `derived from freshness may not meet user needs, which is why
this option is provided.
