How to run with IBFT consensus?

[heypran]

What all changes will I have to make in this repo in order to run the nodes with IBFT consensus instead of RAFT?

I know couple changes -

1. Changing the genesis file
2. Change in command line arguments while running the node.

Anything else? Will the geth version used here suffice for IBFT ? I am not sure..
