> NodeMarkersRegistrationTest.testNodeMarkersRegistration is frequently failing on jenkins
builds in the same spot, with a similar looking logs.
> Although i haven't been able to reproduce these failures locally, I am fairly confident
that the problem is a race condition bug that exists between when/how a new Overseer will
process & clean up "nodeLost" marker's in ZK, with how other nodes may (mistakenly) re-create
those markers in their liveNodes listener.
