Extract basic auth from URL

[hollinwilkins]

URLs that have basic auth included in the origin username:[email protected] should pass the appropriate headers via metadata in the gRPC call.

If I pass a URL like this to gRPC-gateway: myuser:[email protected]/api-call1 I would expect the grpcgateway-authorization and authorization keys to be set with the relevant data, just as if I had passed the username/password via the Authorization: Basic ... header

Nevermind, apparently this way of passing credentials is deprecated.
