The package has some logging that I would class as 'debug', but is using 'info' and is adding noise to my logs.
See [this line](https://github.com/awslabs/aws-embedded-metrics-python/blob/24cc7e50c84a743310b218784ca9a524cead843f/aws_embedded_metrics/environment/environment_detector.py#L60) as an example.
