Ansible Role to gather node UUIDs for node-specfic overrides

Populates the host_vars of the ceph-ansible working directory, as provided by the tripleo-ceph-work-dir role, by mapping each hostname to its UUID. The UUID is determined by running the dmidecode -s system-uuid command on each node with Ansible. This role creates and executes its own playbook. This role sets up the host_vars directory used by ceph-ansible so that TripleO's "node specific overrides" can be used to override a particular parameter for only a subset of hosts. The most popular usecase for this role is to pass a different list of block devices to be used as OSDs for a subset of servers which differ from the majority of servers.
