Full logs from Rolling Update process might be found here: https://gist.github.com/slaskawi/2308b4c5e9bbf523fb3e02a7cc45fa24

Steps to reproduce:
* Start local OpenShift Cluster
* invoke `./init_infrastructure.sh` from https://github.com/slaskawi/presentations/tree/ISPN-7487-reproducer
* invoke `cd transaction-creator && mvn fabric8:run`
* Start Spring Session Demo `cd session-demo && mvn fabric8:run`
* Create a client which inserts data (`watch -n 0.5 curl http://<spring-session-demo-pod-ip>/sessions`) and at the same time invoke the rolling update: `oc deploy transactions-repository --latest -n myproject`
* Observe logs `kubetail -l environment=infrastructure`
