Allow user to set max_stream_count when fetching result using BigQuery Storage API with incremental methods:

  • to_arrow_iterable
  • to_dataframe_iterable

Fixes #2030 🦕

I think it would be more consistent if we use the same docstring as here. It also mentions the effect of preserve_order (in this case self._preserve_order), which I think we should make clear here.

In this case, _preserve_order is automatically set by parsing the queries, and not a user-facing API. I'll update the docstring to mention that effect.

Thank you @kien-truong for adding further support for max_stream_count! I left some comments, and I wonder if you could add some unit tests too (we typically require 100% unit test coverage). You could find similar tests in PR #2039. If you need any help with it, feel free to let me know. I'd be more than glad to help!

Hi, the default code path with the default arguments is already covered by the current tests.
I'll see if I can add tests for when the user manually set the argument when I have time at weekend.

@kien-truong sounds good. The mypy test is also failing, could you fix it too? You can run it by running nox -s mypy in the repo. (You can install nox by pip install nox)

I have added tests to cover user-provided max_stream_count flow and fixed the mypy test as well.

Thanks @kien-truong, the PR mostly looks good. I just have some small question regarding ignored coverage for the tests.
