docstring: Computes the login URL for redirection.
  
  @param string $destination_url The desired final destination URL for the
  user once login is complete. If 'destinationURL' does not
  have a host specified, we will use the host from the
  current request.
  
  @param string $federated_identity The parameter is used to trigger OpenId
  Login flow, an empty value will trigger Google OpenID Login
  by default.
  
  @return string Login URL. If federatedIdentity is set, this will be
  a federated login using the specified identity. If not, this
  will use Google Accounts.
  
  @throws UsersException If there was a problem using the Users service.
