    Create allocation if hostname matches display_name

    To facilitate migration from nova to nova-less
    deployment create an allocation when the display_name
    in the ironic nodes instance_info matches the instance
    name associated with the baremetal node matches the
    hostname provided in the baremtal deployment YAML
    definition.

    Also add a safeguard to not allow creating allocations
    with duplicate names.
