config-download: ensure pacemaker nodes start steps at same time

[James Slagle]

Ansible executes nodes in batches based on the number set in ANSIBLE_FORKS. The default is 5. When deploying with a node count greater than the value of ANSIBLE_FORKS, different nodes can be done at different times on each task.

This can cause a problem with pacemaker nodes where each node must be on the same step at the same time, otherwise the cluster won't properly initialize. We need to fix this to ensure pacemaker nodes always run at the same time.

    Run tasks on primary role first

    This patch adds the primary role name as the first host pattern in the
    individual plays in deploy-steps.j2. This will ensure that the primary
    role will execute tasks first, which is needed so that all Pacemaker
    nodes run the same step at the same time.
