Looking at the latest PRs in moby/moby, common integration-cli tests are failing because they are known flaky in the DockerSwarmSuite. The top ones seem to be:

1. TestAPISwarmLeaderElection Flaky test: TestAPISwarmLeaderElection #32673
2. TestSwarmClusterRotateUnlockKey Flaky test: DockerSwarmSuite.TestSwarmClusterRotateUnlockKey #38885
3. TestAPISwarmRaftQuorum Flaky test: TestAPISwarmRaftQuorum #34988
4. TearDownTest flaky test: DockerSwarmSuite.TearDownTest on PowerPC #33041

@dperny are these failures representative of a bug in swarmkit? The DockerSwarmSuite flaky failures are popping up more often now and are slowing down time to merge PR.
