PreLeader is an intermediate state prior to Leader to apply any uncommitted
transactions on leader change prior to accepting new ones. I would suggest
testing with Boron SR3 as it contains several changes/fixes. I would also
suggest running with org.opendaylight.controller.cluster.datastore.Shard
debug enabled so there's a paper trail in case something goes wrong.
