NO_PROXY support

[dmilosz]

Overview

The library takes provided proxy url or use system configured proxy in environment variable. However, proxies don't work for internal resources and sending request to e.g. localhost or other internal corporate resources fails, depending on proxy configuration.

To do

• Change reading system proxy settings to include NO_PROXY variable https://github.com/microsoft/node-request-light/blob/main/src/node/main.ts#L268-L272
• If requested resource is in NO_PROXY list, don't use proxy agent
