9018b3dc4d raft: let learners vote 
It turns out that that learners must be allowed to cast votes.

This seems counter- intuitive but is necessary in the situation in which
a learner has been promoted (i.e. is now a voter) but has not learned
about this yet.

For example, consider a group in which id=1 is a learner and id=2 and
id=3 are voters. A configuration change promoting 1 can be committed on
the quorum `{2,3}` without the config change being appended to the
learner's log. If the leader (say 2) fails, there are de facto two
voters remaining. Only 3 can win an election (due to its log containing
all committed entries), but to do so it will need 1 to vote. But 1
considers itself a learner and will continue to do so until 3 has
stepped up as leader, replicates the conf change to 1, and 1 applies it.

Ultimately, by receiving a request to vote, the learner realizes that
the candidate believes it to be a voter, and that it should act
accordingly. The candidate's config may be stale, too; but in that case
it won't win the election, at least in the absence of the bug discussed
in:
https://github.com/etcd-io/etcd/issues/7625#issuecomment-488798263.
