Add an option that would allow us specify socks proxy

[emberdart]

Are there any plans to support socks?

Thanks

Does http-client support them?

[emberdart]

Via envs it looks like it does. snoyberg/http-client#262

[mrkkrp]

Since req is built on top of http-client, it should also support the feature is the same way. Do you think something is missing? If so, which form would it take in req?

[emberdart]

Hmm, I thought since there was a httpConfigProxy :: Maybe Proxy field in HttpConfig, that that would suggest there could also be a httpConfigSocksProxy or that this field accepts another kind of Proxy (if you could make some other kind of proxy a Proxy)

[mrkkrp]

I'd accept a PR adding that.

[emberdart]

Okay, awesome. I'll see what I can do.

[emberdart]

Hmm, looks like that that's not the same way that the upstream package works, and I doubt you would want to have System.Environment and setEnv inside this package... I'll be looking for a different way.
