[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.
I just had to set some revision number, to bridge that gap.
```ruby
crowbar_pacemaker_sync_mark "wait-remove_#{role_name}" do
  revision 1000
end
```
