Use sockets.DialerFromEnvironment, as is done in other places, to transparently support SOCKS proxy config from ALL_PROXY environment variable. Requires the *engine* have the ALL_PROXY env var set, which doesn't seem ideal. Maybe it should be a CLI option somehow? Only tested with push and a v2 registry so far. I'm happy to look further into testing more broadly, but I wanted to get feedback on the general idea first. Signed-off-by: Brett Higgins <brhiggins@arbor.net>
