> LeaderElectionContextKeyTest is very flaky -- and on millers beastit reports it shows
a suspiciously close to "50%" failure rate.
> Digging into the test i realized that it creates a 2 shard index, then picks "a leader"
to kill (arbitrarily) and then asserts that the leader election nodes for *shard1* are affected
... so ~50% of the time it kills the shard2 leader and then fails because it doesn't see an
election in shard1.
