[consensus] KUDU-2947 fix voting in case of slow WAL
Before this patch, a follower replica may grant 'yes' vote right after
processing recent Raft transactions even if currently established leader
is alive and well in cases when persisting a Raft transaction in WAL
takes longer than the leader election timeout.
That might lead to multiple successive election rounds even if there
were no actual reason to re-elect leader replicas.
This patch also adds a test to verify the behavior of follower tablet
replicas under the conditions described above. The test was failing
before the patch and now it's now passing.
This is a follow-up to 4870ef20b9a0c729c1d7f16c016c7d91b193e46f.
