Add CentOS SIGs for CentOS Stream 9 to AFS mirrors

In CS9 the layout of the repos has changed and the SIGs repos are in a
separatee directory under centos-stream [1] so we need to add a new
rsync command. These repos includes messaging for rabbitmq-server, nfv
for openvswitch and storage for ceph.
