Roman Puchkovskiy updated IGNITE-22876:
---------------------------------------
    Description: 
Either a specific manager (like CmgDisasterRecoveryManager) or a method in 
ClusterManagementGroupManager needs to be added.

The method signature should look like

CompletableFuture<Void> resetCluster(List<String> newCmgConsistentIds)
 # It accepts consistent IDs of the members forming the new CMG
 # It builds a ResetClusterMessage containing newCmgConsistentIds, existing 
cluster name and a newly generated random cluster ID
 # It then sends this message to each node in the physical topology (including 
itself)
 # Receiving this message, a node saves its contents to the Vault, responds 
with OK and initiates a [restart|IGNITE-22877] of itself
 # The node on which the method is called (the Conductor) waits for all nodes 
to either respond with OK or leave failing to receive the message
 # If the wait finishes successfully without triggering a timeout, the 
Conductor restarts itself
 # If a timeout passes, but the wait above has not finished, then:
 ## If the majority of the new CMG nodes has replied with OK, then the 
Conductor restarts itself
 ## Otherwise, the result is indeterminate, an exception is returned, and the 
user has to manually restart the nodes that did not respond.
