[Baremetal] - Change roles and playbooks names

A few playbooks and the create-vm-nodes role should change the name to
reflect the new reality once the baremetal patches are merged. The
playbooks that must change the name are:

- xci-prepare-virtual.yml
- xci-create-virtual.yml

+create-nodes
+================
+
+This role creates the all nodes required for the XCI deployment. In a baremetal
+deployment, it creates the OPNFV VM and provisions the physical servers. In a
+non-baremetal deployment, it creates the OPNFV VM and the rest of VMs used to
+deploy scenarios. It is based on the bifrost role:
+
+https://github.com/openstack/bifrost/tree/master/playbooks/roles/bifrost-create-vm-nodes
+
+It creates the VMs or provisions the physical servers based on the pdf and idf
+document which describes the characteristics of the VMs or physical servers.
+For more information check the spec:
+
+https://github.com/opnfv/releng-xci/blob/master/docs/specs/infra_manager.rst
+
+
+Flow
+----
+
+The script xci/infra/bifrost/scripts/bifrost-provision.sh will call the
+playbook that starts executing the role:
+
+xci-setup-nodes.yaml
+
+Note that at this stage the pdf and the opnfv_pdf_vm.yml are loaded.
+
+Some distro specific tasks related to variables are done and then the
+prepare_libvirt playbook is run. This playbook, as the name says,
+gets everything ready to run libvirt.
+
+After that, the nodes_json_data dictionary is initialized. This will collect
+the data and finally dump it all into the baremetal_json_file which will be
+read by bifrost in the subsequent role.
+
+The opnfv vm and the rest of vms get created using the xml libvirt template,
+which gets filled with the pdf and opnfv_pdf_vm.yml variables. If there is a
+baremetal deployment, the nodes_json_data gets filled in the
+baremetalhoststojson.yml playbook which basically reads the pdf info.
+
+Finally nodes_json_data is dumped.
+
+Requirements
+------------
+
+The following packages are required and ensured to be present:
+- libvirt-bin
+- qemu-utils
+- qemu-kvm
+- sgabios
+
+
+Warning
+-------
+
+- It is assumed that the opnfv VM characteristics are not described in the pdf
+but in a similar document called opnfv_pdf_vm.yml. There is also an idf
+document opnfv_idf_vm.yml
+
+- All references to csv from bifrost-create-vm-nodes were removed
+
+Role Variables
+--------------
+
+baremetal_json_file: Defaults to '/tmp/baremetal.json'. It contains the
+                     required information for bifrost to configure the
+                     VMs appropriately
+
+vm_disk_cache: Disk cache mode to use by VMs disk.
+               Defaults to shell variable 'VM_DISK_CACHE', or,
+               if that is not set, to 'writeback'.
+
+node_names: Space-separated names for nodes to be created.
+            Defaults to shell variable 'NODE_NAMES'.
+            If not set, VM names will be autogenerated.
+            Note that independent on the number of names in this list,
+            at most 'test_vm_num_nodes' VMs will be created.
+
+vm_network: Name of the libvirt network to create the nodes on.
+            Defaults to shell variable 'VM_NET_BRIDGE', or,
+            if that is not set, to 'default'.
+
+node_storage_pool: Name of the libvirt storage pool to create disks
+                   for VMs in.
+                   Defaults to shell variable 'LIBVIRT_STORAGE_POOL', or,
+                   if that is not set, to 'default'.
+                   If absent, this pool will be created.
+
+node_storage_pool_path: Path used by the libvirt storage pool
+                        'node_storage_pool' if it has to be created.
+                        Defaults to "/var/lib/libvirt/images".
+
+node_logdir: Folder where to store VM logs.
+             Defaults to "/var/log/libvirt/baremetal_logs".
+
+vm_emulator: Path to emulator executable used to define VMs in libvirt.
+             Defaults to "/usr/bin/qemu-system-x86_64".
+             Generally users should not need to modify this setting,
+             as it is OS-specific and is overwritten by
+              os/distribution-specific defaults in this role when needed.
+
+vm_libvirt_uri: URI to connect to libvirt for networks, storage and VM
+                related actions.
+                Defaults to shell variable 'LIBVIRT_CONNECT_URI', or,
+                if that is not set, to 'qemu:///system'.
+                Note that currently connecting to remote libvirt is
+                not tested and is unsupported.
+
+network_interface: Name of the bridge to create when creating
+                   'vm_network' libvirt network.
+                   Defaults to "virbr0".
+                   Name and default of this option are chosen to be the same
+                   as in 'bifrost-ironic-install' role.
+
+opnfv_vm_network_ip: IP for the 'network_interface' bridge.
+                    Defaults to '192.168.122.1'.
+                    This setting is applied only when 'vm_network'
+                    was absent and is created from scratch.
+
+node_network_netmask: Subnet mask for 'network_interface' bridge.
+                      Defaults to '255.255.255.0'.
+                      This setting is applied only when 'vm_network'
+                      was absent and is created from scratch.
+
+Dependencies
+------------
+
+None at this time.
