proxy support

[rogerlz]

Hi,

r10k supports proxy in the r10k.yaml (https://github.com/puppetlabs/r10k/blob/master/r10k.yaml.example)

It would be good to have that feature available for g10k. Any thoughts before I start coding a patch?

Thanks

I really thought I mentioned proxy support in the readme or in the --help output.

Like curl, wget or git you can set the environment variables http_proxy and/or https_proxy for g10k

g10k/forge.go

Line 159 in 394c5f6

proxyURL, err := http.ProxyFromEnvironment(req)

https://golang.org/pkg/net/http/#ProxyFromEnvironment

I'll update the readme.
