add new LWRP to cleanup after role deactivation

- call: barclamp_role
- stops and removes pacemaker resources
- stops and disables services
Ok, ```.to_a``` doesn't work, but i really prefer

```ruby
service_name = if new_resource.service_name.is_a? String
  [new_resource.service_name]
else
  new_resource.service_name
end
```

or 

```ruby
service_name = [new_resource.service_name].flatten
```
