http: client keep-alive for UNIX domain sockets
Makes Connection: keep-alive
behave correctly when making client
connections to UNIX domain sockets.
Prior to this, connections would never be re-used, but the keep-alive would cause the connections to stick around until they time out. This would lead to an eventual EMFILE error due to all the connections staying open. This was due to http.Agent not properly supporting UNIX domain sockets.
