> Reproducer: {{WalModeChangeAdvancedSelfTest.testServerRestartCoordinator}}
> WAL mode change operation initiates an exchange through custom discovery event. The test does the following:
> 1) Initiate constant flow of such events from one node
> 2) Constantly stops current coordinator node and start another one sever node 
> Debug shows the following:
> 1) Remaining client nodes is on exchange X, waiting for new coordinator to send affinity message
> 2) New coordinator is on exchange [X+1], waiting for client to send partition message
