---------------------------------------------------------------------
A preliminary request format is this:
POST /management/v1/cluster/init
{
"metastorageNodes": [
"node1ConsistentId",
"node2ConsistentId"
],
"cmgNodes": [
"node2ConsistentId",
"node3ConsistentId"
]
}
Not sure where to put it, so let it be here for now.

> Labels: ignite-3
>
> As part of the node join protocol, a special Raft group will be created:
> Cluster Management Group (CMG). It is proposed to add a new component that is
> responsible for working with this group. It should perform the following
> actions:
> # Register a message listener in case the group leader is elected and the
> CMG node addresses are sent to all other member of the cluster.
> # If a node is a member of the group and is elected as the leader, it should:
> ## Initialize the group state upon creation: generate a cluster tag and add
> it and the Ignite product version to the state machine.
> ## Listen for join messages and validate incoming requests.
> ## Add new nodes to the logical topology.
> # If a node is not a member of the group, it should:
> ## Send a join request to the group leader.
> ## Process the response and send the "join ready" message after local
> recovery is complete.
