No web proxy support

[cdwt]

We have an environment where we need to access the Internet via proxy, but unfortunately, the tool does not support this setup. Is it complicated to add proxy support using some standard environment variable like HTTP_PROXY?

Let's me take a look to see how hard it is.

In the mean time, the --jwt token generation is local computation which shouldn't need network. https://github.com/google/oauth2l#--jwt

The Go version will be ready soon. If you can send a patch to add proxy support to the Go version, that would be awesome.

The Python version depends on a deprecated library. We don't have bandwidth to fix it.
