[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.
Sounds sensible.  At least, copy'n'paste of code blocks between barclamps is strictly prohibited ;-)  If an LWRP can help avoid that, then it's probably the right thing to do.
