[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'm not sure.  Currently I only see the disadvantage that it turns the keystone barclamp into a "snowflake" which is different to all the others.  What is the advantage to outweigh this?
