[Baremetal] Add baremetal support to create-nodes

Information about baremetal servers is collected for ironic to do
the provisioning. Two main things are done:

1 - baremetalhoststojson.yml fills the json config file fed to ironic
so that it knows how to boot the blades. In the baremetal case, the
create_vm.yml playbook will only create opnfv vm. The variable
vms_to_create holds that information. The variable baremetal_nodes
specifies the physical nodes (empty when non baremetal deployments)

2 - For PXE to work, we create a file called baremetalstaticips that
has the mapping between mac address from servers and its ip. That file
is moved into the dnsmasq config directory
