Worker should catch if Swift not enabled for customer log archiving

[David Shrewsbury]

Swift archiving code in haproxy driver should do a better job of catching and identifying errors, like when Swift isn't available for a given set of auth credentials. Right now, we get a Python Exception thrown that isn't helpful:

2013-04-17 15:55:55,799: libra_worker - ERROR - ARCHIVE failed: <type 'exceptions.AttributeError'>, 'NoneType' object has no attribute 'find'

[David Shrewsbury (dshrews)]

NOTE: This NoneType exception is being thrown by the Swift API library.

    Catch Swift exc's and better container handling.

    Fixes bug 1170110

    If Swift were not enabled for a given set of user credentials,
    the Swift API would throw non-descriptive exceptions. We catch
    those with this change and provide a somewhat better error.

    Also, container creation is handled much better. Before, we were
    creating empty objects within a container. Now, we create the
    container and the object we put is named with the LB ID.
