Orchestrate a devstack
Runs devstack in a multinode scenario, with one controller node and a group of subnodes.
The reason for this role is so that jobs in other repository may run devstack in their plays with no need for re-implementing the orchestration logic.
The "run-devstack" role is available to run devstack with no orchestration.
This role sets up the controller and CA first, it then pushes CA data to sub-nodes and run devstack there. The only requirement for this role is for the controller inventory_hostname to be "controller" and for all sub-nodes to be defined in a group called "subnode".
This role needs to be invoked from a playbook that uses a "linear" strategy.
