[midPoint] Midpoint 4.8 Kubernetes Cluster

[Sven Feyerabend]

Hi,

I can confirm that clustering works.

We have a running 3 node midPoint cluster on top of a bare-metal 
Kubernetes cluster.
The clustering part of your config that you shared is the same that we have.

Also, I don't remember running into this issue during setup of my instance.

Kind regards,

Sven
