By adding our own customized rbd udev rules and ceph-rbdnamer we can create device paths that include the cluster fsid and avoid any ambiguity if the same pool and namespace combination is used in different clusters we connect to. Additionally to the '/dev/rbd/<pool>/...' paths we now have '/dev/rbd-pve/<cluster fsid>/<pool>/...' paths. The other half of the patch makes use of the new device paths in the RBD plugin. The new 'get_rbd_dev_path' method the full device path. In case that the image has been mapped before the rbd-pve udev rule has been installed, it returns the old path. The cluster fsid is read from the 'ceph.conf' file in the case of a hyperconverged setup. In the case of an external Ceph cluster we need to fetch it via a rados api call.
