fix: Several changes were missed when Async queries add cancel status was first merged (#199)

* Added async_execution to async_db/cursor and db/cursor. Added an error, . Added a slot and getter for query_id to BaseCursor. (Temporarily?) edited setup.cfg to ignore flake8 C901: function is too complex.

* Removed ignore C901 from flake8 settings in setup.cfg.

* Fixed a couple of missing arguments in async_db/cursor.py on execute and execute_many calls.

* mypy and black cleanup.

* Removed set_parameters argument from all(?) functions. Started adding logic for SET async_execution.

* Added a bunch of callbacks to cursor tests.

* Pulled out a couple more set_parameters variables from function signatures. Edited callbacks and various tiny things in async test_cursor.py.

* Added, and commented out, server_side_async_url to unit/conftests.py.

* Removed test_set_parameters() from tests/async/cursor.py.

* Removed test_set_parameters() from tests/async/cursor.py.

* Added ability to see which exectute is failing (execute or executemany) on a unit test run.

* Added more explicit error messages to async and sync test_cursor.py modules.

* Added some periods.

* Replaced cursor reset call in async _do_execute().

* Updated query/message tuple decomposition in test_cursor to be more human-readable.

* Fixed a typo and function signature for db/test_cursor_server_side_async_execute() to remove async.

* Removed second hard-coding of query_id in server-side async id callback.

* Needed to add an await to an _api_request() call.

* Used InternalError to error out on no response to async server-side query. Changed AsyncExecutionUnavailableError to generically accept messages.

* Added additional checks on rowcount and description in test_cursor_server_side_async_execute().

* Added QueryResponse class.

* Minor changes requested on PR.

* Added an OperationalError is asynchronous query response is missing query_id.

* Had a typo.

* Added a warning if asyc_execution is set via a SET parameter rather than being sent in as an argument to execute(). Moved set parameter validation to its own function to deal with flake8 complaints re _do_exectute() being too complex.

* Started adding test_cursor_async_execute_error().

* Updated query_url argument in test_cursor_async_execute_error().

* Added AsyncExecutionUnavailableError on server-side async query execution for multi-statement queries.

* Seem to have dealt with auth issues in test_cursor_async_execute_error, but getting invalid set parameter on use_standard_sql. Also added # noqa: C901 to parse_type() definition in _types.py because flake8 was suddenly freaking out about it.

* Added all necessary set params to url string in test_cursor_async_execute_error().

* Cleaned up string input in test_cursor_async_execute_error().

* Now no token error.

* Multi-statement queries now error out correctly.

* Reworked a string to try to get commit/push to work.

* Had to add an extra auth callback to get all cursor.execute() calls to work. All error tests for async_execution should now be tested correctly.

* Removed some parameters from various fns in unit/async_db/test_cursor that I noticed were extraneous. Too bad mypy or flake8 isn't catching these :-/.

* Added error check for missing query_id on async_execution. A little bit of cleanup, also Black seems to have made a change or two.

* Fixed error for empty response.json on asynch execution. Also changed the use of SET async_execution to an error and included test for that error.

* Fixed error for empty response.json on asynch execution. Also changed the use of SET async_execution to an error and included test for that error.

* Fixed error for empty response.json on asynch execution. Also changed the use of SET async_execution to an error and included test for that error.

* Added a test to check that an server-side asynchronous execution returns a string, as a non-sync-execution query would return rowcount as an int.

* Added an integration test to check that an server-side asynchronous execution returns a string, as a non-sync-execution query would return rowcount as an int.~

* Added cancel() to async/cursor.py. Also fixed an error where I was getting empty query ids back from server-side async exectutions, and added an error for that case.

* Forgot that I'd commented out most of test_cursor.py.

* Trying to get rid of coroutine 'BaseCursor.execute' was never awaited warning. Not yet successful.

* Added unit tests for cancel and cancel errors.

* Fixed a mistake that would have failed the cancel() integration test.

* Fixed several imports that had disappeared (maybe during a merge?). Also fixed an error in test_ss_async_execution_cancel().

* get_status() and two unit tests are added. Integration test is failing with json that has correct field names but empty fields.

* Added a new QueryStatus, NOT_AVAILABLE, because checking status will return empty result the first few times. Fixed some issues with the unit tests and updated the integration tests for get_status().

* Added a comment.

* Updated a comment.

* Added stub fn for async execution fetch.

* Keep forgetting to uncomment test code and the pre-commit checks are removing imports. Left in some extra calls to time() and sleep() for now.

* Removed some extraneous testing code.

* Updated test_ss_async_execution_get_status() after Yoni pointed out that DDL operations will always return empty JSON. Now using an INSERT instead.

* Had to comment out test_ss_async_execution_get_status(), as it basically entered an infinite loop.

* Added ability to specify output_format in _api_request(), as status requests will fail if it is set.

* First set of requested changes on PR.

* Removed noqa on _do_execute().

* Renamed _find_async_problems() to _validate_ss_async_settings(). Removed test_cursor_server_side_async_cancel_error from integration tests.

* Moved call to _validate_ss_async_settings() into try.

* Added asyncio_mode=auto to pytest config in config.cfg, because I was tired of the continual warnings from pytest.

* Changed long query in test_queries_async integration tests. Paused execution of after cancel() to ensure I pick up the correct status message. Now sending output_format= on some calls to _api_request().

* Updated all unit tests that test SET parameters to not have output_format in the url.

* Changed query_loop() in integration tests/async/test_queries to check for more than one status before exiting the loop.

* Noticed that test_anyio_backend_import_issue() was commented out in sync/test_queries.py. That was done bc it won't run on my laptop, but it shouldn't have been committed that way.

* Added query tests to integration/dbapi/sync/test_queries.py. Changed async_exectution test to not count SET statements as queries when determining whether a query is multi-statment. Trying to get sleepEachRow() to work for long aync execution queries.

* Added query tests to integration/dbapi/sync/test_queries.py. Changed async_execution test to not count SET statements as queries when determining whether a query is multi-statment. Trying to get sleepEachRow() to work for long aync execution queries.

* Now errors out when use_standard_sql=0 rather than when it equals 1. This is because if it's off no log entries are written to query_history. Still using a long insert for integration tests on server-side async queries. Added and edited to unit tests for use_standard_sql correctness.

* Changed order of synchronous unit tests to move all server-side async tests to end.

* Changed order of asynchronous cursor unit tests to move all server-side async tests to end.

* Reordered integration and unit test modules to move all server-side async tests to end of modules to facilitate merging main.

* Moving JSON_OUTPUT_FORMAT outside of _api_request (#196)

* Updated docs to include information on server-side async query execution.

* Updated external table mention in comments and removed sentence in docs. Updated dictionary update in _api_request() to make mypy happy.

* Made a change to server-side execution explanation for clarity and to explain usefullness of that functionality.

* Renamed a function and moved table create and drop out of test_queries.py and into conftest.py. Currently name not defined error. Maybe it's in the wrong conftest file?

* Damn. I merged and there were uncommitted changes.

* Removed two typos in docsrc/connecting_and_queries.rst.

* Updated the description of both server-side and client-side async in the docs to clarify the differences.

* Created setup and teardown fixture for creating and dropping test_tbl in integration tests.

* Damn. I merged the PR to main and there were uncommitted changes.

* Removed two typos in docsrc/connecting_and_queries.rst.

* Updated the description of both server-side and client-side async in the docs to clarify the differences.

* Created setup and teardown fixture for creating and dropping test_tbl in integration tests.

* Typo.

* Trying to get a long enough query. Now I'm getting parse errors that I can't figure out.

* Just skipping integration tests on cancel and get_status().

* Cleaned up two long strings and commented out assert in integration test db/sync/test_queries::test_server_side_async_execution_get_status.
