[RHOCP 4] kieserver pod taking long time to get the IP assigned

Issue

• While trying to create a kieserver pod, using a customer deploymentconfig, the pod goes into the ContainerCreating state, and the IP field is showing none.

  $ oc get po -o wide
  NAME                                                                                   READY            STATUS                    RESTARTS   AGE        IP                        NODE                                  NOMINATED NODE      READINESS GATES
  parereunico-dev-881-kieserver-test-26-wlxc8         0/1        ContainerCreating   0          26s                       <none>         ocp4-7s8wr-worker-wltdz                 <none>                        <none>
  

• But in the pod logs we can see that the IP is getting assigned then tried to ping the IP from the node where the pod is scheduled it was unable to connect, but after some time the pods get up and running and also able to ping from the node.
