[RHOCP 4] Ability to specify multiple NodePort ranges in OpenShift

Issue

• How to specify multiple NodePort ranges in Red HatOpenShift Container Platform?

• The existing parameter serviceNodePortRange should specify the range of ports that are opened up externally, but a second parameter: serviceNodePortAllocationRange would allow specifying the range available for dynamic NodePort allocation.

  For instance, the range 7000-31999 is only available for static NodePort allocation while 32000-32768 would be dynamic, when a NodePort value is not specified in the service definition:

  oc patch network.config.openshift.io cluster --type=merge -p 
  '{
   "spec":
     { "serviceNodePortRange": "7000-32768" 
    serviceNodePortAllocationRange : “32000-32768”
     }
  }'
  

• Is it possible to separate NodePort allocation range from the available range in OpenShift?
