  1. Ignore RequestVote when leader is established. 

    This behavior is described in the original Raft paper and is required to
prevent removed nodes from disrupting the cluster.

This causes other problems though, as a split node may trigger election
which is rejected but leaves it with a future term.  The generally
accepted solution for this appears to be the use of PreVote RPC to avoid
election that can never succeed.
