Add Nova config for os_ironic role
This patch configures Nova for use with Ironic, noting that without moving to cells, an openstack-ansible install can support only one type of hypervisor at a time (i.e. kvm or ironic etc). Setting the nova_virt_type determines whether Nova is configured for Ironic. If it is left unset, the default kvm hypervisor is used. The nova virtualization types have all been moved into a single nova_virt_types data structure which is used to define facts for a specific supported virtualization type. This change is compatible with older versions of overrides as the virt type values are used to set host facts which could also be set using user variables or any other means to predefine a default value.
