If during cluster creation or update, one or more nodes cannot be created by Nova (because, for example, the project runs out of quota, or Nova runs out of suitable hypervisors), the cluster stalls with CREATE_IN_PROGRESS status. The status_reason in this case is not helpful as it only reports the previous step which succeeded. This patch adds a check of each individual machine status looking for machines which are not ready and reports any reason found. This can result in useful status_reason messages such as 'error creating Openstack instance ... Quota exceeded for instances'
