[Ready for Review] after role deactivation stop services and remove HA resources

Once that PR is reviewed and accepted, I can start to finish the feature for the other barclamps as well. 
So please have a look at this one, as it will be similar to the other barclamps.
If it's not the same across all cookbooks then I really don't see the point for complicating this by making it general. You're looping over a one-item hash. I don't think you need either the loop or all the variables:

```ruby
pacemaker_primitive name do
  action [:stop, :delete]
  only_if "crm configure show #{node['keystone']['services']['server']}"
end
```

Same for the other block.
