Baremetal deploy - user playbook interface

Extend the overcloud node provision command to run
ansible playbooks defined in the baremetal deployment
definition against the provisioned nodes.

To ensure the playbook is applied prior to node network
configuration set 'pre_network: true'. Additonal ansible
vars can be defined as 'extra_vars' for each ansible
playbook definition.
