When instanciating an osd, we now pass clusterInfo which basically
represents a collection of information about a particular Ceph cluster. Rook uses information
// about the cluster to configure daemons to connect to the desired cluster.
From clusterInfo, we use the CephVersion which helps us putting
conditions for our code execution.
