Normalize url without port with schema default port

In function get_bare_url, it will assert url startswith base_url,
if base_url is 'http://neutron.openstack.svc.cluster.local:80/',
while url is 'http://neutron.openstack.svc.cluster.local/v2.0/router/...',
it will raise error. here need to add default schema port 80 to url to
fix this problem.
