    Fix Version/s:     (was: 2.8)

> Cluster ID and tag: properties to identify the cluster
> ------------------------------------------------------
>                 Key: IGNITE-12111
>                 URL: https://issues.apache.org/jira/browse/IGNITE-12111
>             Project: Ignite
>          Issue Type: New Feature
>            Reporter: Sergey Chugunov
>            Assignee: Sergey Chugunov
>            Priority: Major
> To improve cluster management capabilities two new properties of the cluster are introduced:
> # A unique cluster ID (may be either a random UUID or random IgniteUUID). Generated upon
cluster start and saved to the distributed metastorage. Immutable. Persistent clusters must
persist the value. In-memory clusters should keep the generated ID in memory and regenerate
it upon restart.
> # Human-readable cluster tag. Generated by default to some random (but still meaningful)
string, may be changed by user. Again survives restart in persistent clusters and is regenerated
in in-memory clusters on every restart.
> These properties are exposed to standard APIs:
> # EVT_CLUSTER_TAG_CHANGED event generated when tag is changed by user;
> # JMX bean and control utility APIs to view ID and tag and change tag.
