## What this does
The Tableau Server Client library has supported an `incremental` flag on
both `datasources.refresh()` and `workbooks.refresh()` for a while now, but the
`TableauOperator` had no way to pass it through every refresh was always a full
refresh.
This adds `incremental: bool = False` to the operator. When you set it to
`True`, the operator will trigger an incremental extract refresh rather than a
full one, which is useful when your datasource is configured for incremental
refresh in Tableau Server.
Example usage:
```python
TableauOperator(
task_id="incremental_refresh_sales",
resource="datasources",
method="refresh",
find="my_datasource",
match_with="name",
incremental=True,
)
```
## What didn't change
Everything else behaves exactly as before. The incremental param is only
forwarded when method="refresh" delete, tasks.run, and all other paths are
completely unaffected. The default is False so no existing DAGs need to change.
Tests
Updated four existing test assertions to include the now-explicit
incremental=False kwarg (they would have started failing without this).
Added test_execute_datasources_incremental and
test_execute_workbooks_incremental to verify incremental=True is correctly
passed through to the underlying library call.
