Allow passing a non-SDK LoggerProvider to the SDK EventLoggerProvider

[alexmojaki]

Here:

opentelemetry-python/opentelemetry-sdk/src/opentelemetry/sdk/_events/__init__.py

Lines 68 to 70 in a7fe4f8

	class EventLoggerProvider(APIEventLoggerProvider):
	def __init__(self, logger_provider: Optional[LoggerProvider] = None):
	self._logger_provider = logger_provider or get_logger_provider()

LoggerProvider is from opentelemetry.sdk._logs, not the API opentelemetry._logs. This is needed for things like this:

opentelemetry-python/opentelemetry-sdk/src/opentelemetry/sdk/_events/__init__.py

Lines 85 to 86 in a7fe4f8

	def shutdown(self):
	self._logger_provider.shutdown()

I've defined a subclass of the API LoggerProvider. A subclass of the SDK provider class wouldn't make sense in my case. I'd like to pass instances of my subclass to EventLoggerProvider. In addition the logger provider defaults to get_logger_provider() which might not be an SDK provider, so the types are buggy.

Most of the logic isn't tied to the SDK LoggerProvider. Where it is, it could do something like:

if isinstance(self._logger_provider, SDKLoggerProvider):
    self._logger_provider.shutdown()

or just:

try:
    self._logger_provider.shutdown()
except (AttributeError, TypeError):
    pass
