Problem Summary:

if an iceberg has a branch named `branch1` and a tag named `tag1`, you
can query `branch1` or `tag1` by these ways:
```sql
-- query 'branch1'
select * from tb FOR VERSION AS OF 'branch1';
select * from tb@branch(branch1);
select * from tb@branch('name'='branch1')

-- query 'tag1'
select * from tb FOR VERSION AS OF 'tag1';
select * from tb@tag(tag1);
select * from tb@tag('name'='tag1')

```
