    Catch InvalidURL when requesting store size

    If location URL looks like scp address:
    http://some_address:~/some_image then glance accepts this address
    and creates a malformed image.
    The problem here is because python http_client lib is trying to
    recognize '~' as port but it is not acceptable port name.
    The lib generates an InvalidURL exception but this exception is
    hidden in one of universal catchers(except Exception).
    We need to validate port name (is present before passing it to
    http_client lib.
