Fix NoProxy configuration

[BradyShober]

Fixes #441

The !proxy.equals(Proxy.NO_PROXY) check does not appear to catch all cases that it should. Explicitly pass the Jenkins No Proxy list through to the client configuration to handle the cases that get past that check.

Testing done

Tested on our live instance with our No Proxy list and confirmed traffic wasn't being sent to the proxy as expected.
