skip check, if its dependency failed

[lukpueh]

Right now, dependent checks run as soon as their dependency check finishes, even if it finished with an error. The dependent check will then only fail, when it tries to access its dependency check's missing result data in the global context.

Let's propagate the error, and skip dependent checks.

Context:

Error is caught and not propagated here:

rsrr/src/rsrr/runner.py

Lines 34 to 39 in d63b6a3

	try:
	value = await check.run()
	ctx.data[check_id] = value
	except Exception as e:
	logger.error(f"{check_id}: {e}")

Error should be handled somewhere here:

rsrr/src/rsrr/runner.py

Lines 67 to 75 in d63b6a3

	tasks = [
	run_check(check_id, check_cls, ctx) for check_id, check_cls in ready.items()
	]
	wave_results = await asyncio.gather(*tasks)
	# Record results and mark as completed
	for check_id, result in zip(ready.keys(), wave_results):
	completed.add(check_id)
	del pending[check_id]
