Add auth support for proxy downloads

[kchodorow]

Should fix #587.

RELNOTES: Support for downloading remote resources through proxies by setting HTTP_PROXY (or HTTPS_PROXY).

Shouldn't no password be a valid case?

I couldn't find documentation about it. Does Java need to even know about the username if the password isn't set?

I have no idea. Well I guess it does not hurt to throw an error there.

LGTM. Should I import it or will you do it?

[kchodorow]

Thanks, I'll do it.

No password is indeed a valid case. I'm using it everywhere (apt-get, git, ...). I am helping myself out here with a username:123 setting.

Does bazel support auth? I cant seem to get my auth required prox-ied computer to work, but my non auth prox-ied VM works?
