"Defaulting to non-proxy environment" log warning

[worpet]

We frequently see lines with this message in our logs:

WARN Defaulting to non-proxy environment

We have traced the source of these to the below Authorize.net code:

https://github.com/AuthorizeNet/sdk-java/blob/487462da57ab1c1285ad345aefcca577360de55b/src/main/java/net/authorize/util/HttpClient.java#L134-L165

It seems like this should be an INFO rather than a WARN. We want to keep our log threshold at WARN to be able to see potential problems, but then we end up with mostly these "non-proxy environment" lines.

Found others complaining here: https://community.developer.authorize.net/t5/Integration-and-Testing/quot-Non-proxy-quot-from-AuthNet-SDK-is-spamming-our-logs/td-p/71855.
