Bmbouter update celery kombu deps

This PR does 3 things:

1.  Add a bandaid fix to the qpid_transport.patch that will cause hard Exceptions to not be raised related to bug [1086130](https://bugzilla.redhat.com/show_bug.cgi?id=1086130).

2.  Introduce a new patch for python-celery that solves celery/celery#1973

3.  Updates the README for both python-kombu and python-celery to document these patches.  This is mainly so we know when to remove them.

Both of these RPMs have been built with tito, smoke tested using a rpm sync, and tagged with tito.  The tags have been pushed and are:  python-kombu-3.0.13-3.pulp and python-celery-3.1.9-2.pulp
