// CertificateLockFile adds a new certificate lock on the given Client and
// Config that ensures that a server's certificate is signed by the same CA
// from connection-to-connection. This is helpful when connecting to servers
// with self-signed certificates.
//
// If filename does not exist, the server's certificate chain will be written
// to that file. If it does exist, certificates will be read from that file and
// added to RootCAs in config's TLSConfig.
//
// Example:
//
//  if firstConnectionToServer {
//      // Allow self-signed certificates to be accepted on the initial
//      // connection.
//      config.TLSConfig.InsecureSkipVerify = true
//  }
//  gumbleutil.CertificateLockFile(client, &config, filename)

//      panic(err)
