What happened?

#4112 introduced a regression and currently it is not possible to initialize integration without also calling logging.basicConfig() as described here:

https://opentelemetry-python-contrib.readthedocs.io/en/latest/instrumentation/logging/logging.html#manually-calling-logging-basicconfig

To enable fields that link to tracking from logs we need to enable set_logging_format:

                    if set_logging_format:
                        record.otelSpanID = format(ctx.span_id, "016x")
                        record.otelTraceID = format(ctx.trace_id, "032x")
                        record.otelTraceSampled = ctx.trace_flags.sampled

But that option also calls logging.basicConfig() which is undesired if one has a specific configuration:

        if set_logging_format:
            log_format = kwargs.get(
                "logging_format", environ.get(OTEL_PYTHON_LOG_FORMAT, None)
            )
            log_format = log_format or DEFAULT_LOGGING_FORMAT

            log_level = kwargs.get(
                "log_level", LEVELS.get(environ.get(OTEL_PYTHON_LOG_LEVEL))
            )
            log_level = log_level or logging.INFO

            logging.basicConfig(format=log_format, level=log_level)

Steps to Reproduce

Enable loggin integration with set_logging_format=True

Expected Result

logging.basicConfig() is not called

Actual Result

logging.basicConfig() is called
