get a proper response if middleware not installed

if objectquery middleware is not installed on object or container server some nonsense responses can come out
now proxyquery will try to detect that and issue HTTP 503 with a proper error message

configparser: fix pep8 violations
fix cors problems

ClusterController is a child class of ObjectController
it needs to have the same instance properties
because the instance is created by middleware and not the Proxy Application __init__ was not called with proper arguments
sometimes it worked (because middleware has some properties of Proxy App), sometimes not
now the __init__ is called correctly and all the methods of the parent class should work as expected

cors wrapper `cors_vaidation` was using references to Proxy App in the controller code
when properties were restored `cors_validation` started working as expected

take note, that `test_cors()` test case has some commented out code
it's because of bug in Swift (fixed in current master, cannot really find a specific commit, for some reason) and is not fixed in 1.13.1, which we use for testing and deploy
you can easily test it by checking out `master` and `1.13.1` and running the commented out test on both
