#331
Was based on a false recognition. What
get_election_timeoutshould return is not the leader election timeout but the random timeout before becoming a candidate. This should be fixed.Also, the code is bit unclear, which requires refactoring.
How to decide the timeout is very difficult problem because if we take an uniform distribution between [0,1000ms] then it will not have any guarantee that the election converges if there are 1000 nodes in a cluster.
