Add setQuerySettings tests

[alinaliBQ]

This change adds tests for the setQuerySettings command operator. In order to define the SettingsTestCase class, I renamed query-planning to query_planning. Reason is that hyphens aren't allowed in identifiers, so directories that need to be imported must use underscores instead.

Add command operator tests for setQuerySettings. Tests database setQuerySettings behavior, output collection, syntax, and expected errors.

• Add compatibility test for setQuerySettings #409

Edit: replica_set is needed because query settings are not supported on standalone instances

Reasoning

component from path globs (test-coverage, test-framework); effort from diff stats (3863+1 LOC, 31 files); LLM: Adds new test coverage for the setQuerySettings command operator, covering behavior, output, syntax, and error cases — a functional test expansion across multiple test scenarios.

If a label is wrong, remove it manually and ping @patty-chow so the rules can be tuned. The bot will not re-label items that already have component labels.

1. Please use @pytest.mark.no_parallel. The test cases can interact each other.
2. Please rebase and use @pytest.mark.requires(...)

[alinaliBQ]

@eerxuan I have added @pytest.mark.no_parallel and rebased to use @pytest.mark.requires(change_streams=True).

[eerxuan]

Why does this feature tests require change_streams? Can add a new capability if needed.

[alinaliBQ]

change_streams is needed because query settings are not supported on standalone instances.

[eerxuan]

So you need a capability called "query_settings" which only supported under replicaset target.

Ok, I have looked and cluster_admin seems appropriate here, so I changed to use it instead of change_streams.
