Restarting services that are connected to qpidd.
A qpid exchange that was in use is not deleted, resulting in a leak of exchanges on the qpid broker
This patch adds an option that allows you to switch OpenStack's qpid client code over to a different way of operating that solves this issue. It is an option because it is not backwards compatible with older versions of the code.
No more exchanges will be leaked on the qpid broker.
