playbooks: seperate cluster_machines and standalone_machines

As it was done in the debian branch, use cluster_machines and
standalone_machines in Ansible hosts.

cluster_machines: is for SEAPATH machines which take part of a cluster
    (hypervisors and observers).
standalone_machines: is for SEAPATH machines which not take part of a
    cluster (standalone hypervisors and virtual machines).
