Process loss of slot ownership in cluster bus When a node no longer owns a slot, it clears the bit corresponding to the slot in the cluster bus messages. The receiving nodes currently don't record the fact that the sender stopped claiming a slot until some other node in the cluster starts claiming the slot. This can cause a slot to go missing during slot migration when subjected to inopportune race with addition of new shards or a failover. This fix forces the receiving nodes to process the loss of ownership to avoid spreading wrong information.
