Raft implementation?

[cameronelliott]

@vitorenesduarte This is an insanely great piece of work, especially if Tempo turns out to be bug-free.
(This is outside my area, so, I can't evaluate that. )

One thing that would be fantastic to see in addition to the six protocols implemented, is the popular 'Raft'.
Maybe I am missing a reason it wouldn't fit into this evaluation framework, but it seems this would be
enhanced a lot if a Raft back-end could be implemented.
