// This function translates endpoints names supported by etcd server into
// endpoints as supported by grpc with additional information
// (server_name for cert validation, requireCreds - whether certs are needed).
// The main differences:
//   - etcd supports unixs & https names as opposed to unix & http to
//     distinguish need to configure certificates.
//   - etcd support http(s) names as opposed to tcp supported by grpc/dial method.
//   - etcd supports unix(s)://local-file naming schema
//     (as opposed to unix:local-file canonical name used by grpc for current dir files).
//   - Within the unix(s) schemas, the last segment (filename) without 'port' (content after colon)
//     is considered serverName - to allow local testing of cert-protected communication.
