[Plugins] Wrong task yaml for glusterfs plugin is used

[Tatyanka]

Steps to reproduce:
1.Download lates glusterfs plugin
2. Install it on master node
3. Deploy simple environment with enapled glusterfs plugin:
1 controller + 1 compute + 1 cinder
4. Run ostf , create manually volumes

Actual result:
we have next task.yaml for this plugin
# This task is required for controllers only
- role: ['controller']
  stage: post_deployment
  type: puppet
  parameters:
    puppet_manifest: puppet/site.pp
    puppet_modules: puppet/modules/
    timeout: 360

But actually cinder-volume service is running on cinder node, as result we enable glusterfs driver for cinder on controller and do not enabled it in cinder node (also related to glusterfs shares configs), so that openstack code to store volumes on remote fs never invoked

Expected:
Task.yaml should consist cinder role as well

    Change role to cinder

    We slightly miss that fact than cinder should connect to GlusterFS
    from node which hosts openstack-cinder-volume service. In our case
    it is not controller, but cinder node. So, we just change that role
    in tasks.yaml.
