growvols playbook fail 'ERROR! Specified hosts and/or --limit does not match any hosts' if role Count is 0.

[Harald Jensås]

Deploying with count == 0 in baremetal_deployment.yaml fails as there is an attempt to apply the growvols playbooks to a role (group) that does not exist.

- name: Controller
  count: 3
- name: Compute
  count: 0

    Don't run playbooks if role count == 0

    There is no reason to try to run playbooks limited
    to a role name when the role count is zero. It
    actually fails because no hosts match.

    Add a check to skip roles with count == 0.
