Pull Request Overview

Enable running all non-local tests against Confluent Platform/Cloud by refactoring topic‐creation helpers, introducing a new test runner script, and updating CI behavior

• Add test_can_kafka_cmd and refactor test_can_create_topics to fall back to CLI tooling when AdminAPI is unavailable
• Change hardcoded replication factor 1 to -1 (broker default) in all test topic‐creation calls
• Add run-tests-confluent-kafka.py, update dependencies, and adjust Semaphore CI to return code 130 for skipped jobs

• Using return 130 in a top-level shell command may be invalid; use exit 130 to properly terminate the script with the intended status code.

              return 130;

The script checks for '-l' but then passes '-L' to run-test-batches.py. Change the check to if '-L' in args: (or accept both) so local tests are correctly excluded.

Suggested change

	if '-l' in args:
	if '-l' in args or '-L' in args:

[nitpick] The replication factor argument -1 is a magic number; consider defining a named constant (e.g., DEFAULT_REPLICATION_FACTOR) or a small wrapper to improve readability and reduce duplication.

Suggested change

	test_create_topic_wait_exists(NULL, topic, 1, -1, 5000);
	test_create_topic_wait_exists(NULL, topic, 1, DEFAULT_REPLICATION_FACTOR, 5000);

[nitpick] Pin httpx to a specific version in requirements.txt (e.g., httpx==0.24.0) to avoid unexpected breakage from future releases.

Suggested change

	httpx
	httpx==0.24.0
