The module used to simply "import swift", and then reference
the classes:
swift.common.middleware.catch_errors.CatchErrorsMiddleware
swift.proxy.server.Application
in order to very that the WSGI services loaded the proper filters and
apps.
However, those references only happen to work, as the WSGI loading
would properly import the rest of the path so that the namespace
reference would be okay. If the WSGI configuration were to change, or
if the behavior of WSGI broke, instead of of seeing the actual failure
condition, a module attribute error would result instead:
AttributeError: 'module' object has no attribute 'middleware'
The referenced names are now properly imported with this change to
avoid misleading error conditions.
