[Blocked by crowbar-revision issue] 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.
This part should always be done; it's not because the node is a member of the cluster that keystone is deployed with HA. So it's safer to always do this bit of code :-)
