allow user to provide additional parameters

user can provide auth_type, redirect_uri(already can provide) and scope
in one array.
the main purpose is to let user provide parameters like auth_type while getting login_url 
for example 
$parameters = [
     'scope' => 'scopes , string or array',
     'redirect_uri' => $route,
     auth_type' => 'reauthenticate',
]
