That is an interesting idea. But I'm afraid that this can't be used in 
TripleO use-case. We would have to keep the whole cluster definition as 
a static file which would be included when building overcloud image. 
Keeping this static definition up-to-date sounds like a complex task. 
Also this would make impossible any customization based on used 
elements. For example if there are 2 elements which use pacemaker - 
neutron-l3-agent and ceilometer-agent-central, then I couldn't use them 
separately.
