Current issue : calico-crd depends on namespace_defs.
namespace_defs depends on cluster_machines_ready
cluster_machines_ready wait for machines ready which are not ready until calico are up&running

Note : We should perhaps rename calico-depends-on-cluster-machines-ready (and add a condition related to kubeadm ?)
