adding support for no_proxy environment variable

[jacklty]

Could you add support for no_proxy environment variable please? so we are able to bypass proxy for specific url pattern?

Thanks

FYI: Similar request was made to axios as well but it yet not be part of official release - axios/axios#434

This completely breaks gaxios on machines behind corporate proxies. Is there no way to work around this?

@csvan @jacklty could you describe the expected behavior of no_proxy with a bit more detail?

I gather you provide a list of domains that should not have https_proxy or http_proxy populated for them?

[csvan]

@bcoe precisely, it could look like this:

export no_proxy=localhost,127.0.0.0/8,::1,.mysub.mydomain.com,myotherdomain.net

Among others, node-fetch (at least seems) to respect it when used on its own.
