Update or remove jgroups cluster identification message

[pablocarle]

Is your feature request related to a problem? Please describe.
The cluster node ID in jgroups is read from system calls, if the hostname read this way does not match the one configured in hosts
it may lead to confusion even if the feature is working.

Example message:

-------------------------------------------------------------------
GMS: address=<HOSTNAME>-48761, cluster=zowe-cluster, physical address=<IP Address>:7098
-------------------------------------------------------------------

Describe the solution you'd like
Two alternatives I can think of are either remove this identifier altogether or use a feature in jgroups which allows to use a UUID for the node name instead of hostnam read from system.

Describe alternatives you've considered
There doesn't seem to exist a way to customize the ID with a set value.

It looks like the UUID for nodes is a better choice based on what you are saying.

Do I understand the proposal correctly?

Yes, the proposal is to update the jgroups settings to use a UUID as node identifier.
