Flaky opentelemetry-sdk tests

It looks like there something off regarding the shutdown of a span processor and some issues with the metric exporter as seen in the following logs. The failures and the errors we have below looks unrelated though. ``` =================================== FAILURES =================================== __________ TestEventLoggerProvider.test_event_logger_provider_default __________ self = <tests.events.test_events.TestEventLoggerProvider testMethod=test_event_logger_provider_default> def test_event_logger_provider_default(self): logger_provider = LoggerProvider() set_logger_provider(logger_provider) event_logger_provider = EventLoggerProvider() > self.assertEqual( event_logger_provider._logger_provider, logger_provider, ) E AssertionError: <opentelemetry.sdk._logs._internal.LoggerProvider object at 0x7f4f07441690> != <opentelemetry.sdk._logs._internal.LoggerProvider object at 0x7f4f075e3070> opentelemetry-sdk/tests/events/test_events.py:45: AssertionError ------------------------------ Captured log call ------------------------------- WARNING opentelemetry._logs._internal:__init__.py:425 Overriding of current LoggerProvider is not allowed ________ TestParentChildSpanException.test_child_parent_span_exception _________ self = <tests.trace.test_trace.TestParentChildSpanException testMethod=test_child_parent_span_exception> def test_child_parent_span_exception(self): """ Tests that a child span does not have its status set to ERROR when a parent span raises an exception and the parent span has its ``record_exception`` and ``set_status_on_exception`` attributes set to ``False``.
