   @elek This new interface actually looks nice! I have a refactor plan for OM 
and SCM Ratis chain. I will try to leverage with it in the refactoring work. 
The current way to populate configs needs some changes.

   @elek Hey Marton,
   So far the doc work is ongoing in parallel with prototyping.
   The doc still needs improvements and I will find time to work on that. 
   This patch is only to work on a prototype of SCM HA to get a feeling of it. 
To have Ratis server and state machine for SCM doesn't have debates. Current 
discussion for design is to collect how to handle Raft transaction for all 
different types of actions and reports on SCM. Besides going thru the current 
code base to make analysis, I'm also probing by prototyping. I start off 
implementing a stand alone Ratis Server and make steps. 
   
   I will try to finalize the design doc and schedule a call with the community 
to include more guys.
