Fix failed AsyncioTest.test_send_failure and clean up tests

[BewareMyPower]

After apache/pulsar#23291, which is included in Pulsar 4.0.0, when the tenant does not exist, the broker will respond with BrokerMetadataError, which is retryable.

Before that, the error code is AuthorizationError, which is not retryable so that create_producer will fail immediately.

This patch fixes the test_send_failure to assert the error is Timeout. Additional, separate some tests from pulsar_test.py:

1. debug logger tests will affect other tests so that all tests will print debug logs
2. running schema_test in pulsar_test might have unexpected failures like

I think this is a breaking change that should be reverted in newer releases. But for now, let's pass the tests for now.
