Background & Goal

In part I https://issues.redhat.com/browse/OCPSTRAT-1530 we will expose the tenacy option on the nodepool but won't pin to host-ids. In this feature, we should make the changes to pin to specific host IDs. 

Use-cases

One of the use-cases is Windows licenses for customer VMs (OCP-Virt use-case). In this scenario, each host in a machine pool needs to have the same host allocated at all times. This is crucial for upgrade scenarios, where the same host ID must be allocated to ensure Windows license compliance.
