xci: roles: create-vm-nodes: Add role for creating XCI VM nodes

Add a new role based on the bifrost one to create nodes for the bifrost
virtual deployments. This role will install and configure libvirt on the
host, download a prebuilt OPNFV VM image and deploy the OPNFV VM using
that image. Moreover, it will create the rest of the nodes for the
virtual deployment which will be configured by bifrost later on.
