HonahX opened a new pull request, #498:

This draft PR experiments a possible implementation for
`CreateTableTransaction`. At this early stage, I will focus on the high-level
requirements and correctness to support staged creation and commit the staged
table. The new APIs for `CreateTableTransaction` are subject to change.
Just for your convenience, the current PR:
On Table Side:
- Add `StagedTable` which represents a uncommitted table, inherits `Table`
and disables table scan.
- Add `CreateTableTransaction` which inherits `Transaction`, takes in a
`StagedTable` and add initial create table updates to the `self._updates`
- Other helpers to help build metadata from a chain of updates
On Catalog Side:
- Add `_create_staged_table` API which returns a `StagedTable`
- Add `create_table_transaction` API
- Add a experimental implementation for GlueCatalog
The tentative API looks like
```python
with test_catalog.create_table_transaction(identifier, table_schema_nested)
as txn:
with txn.update_schema() as update_schema:
update_schema.add_column(path="b", field_type=IntegerType())
txn.set_properties(test_a="test_aa", test_b="test_b",
test_c="test_c")
```
Appreciate any initial reviews, suggestions and thoughts!
