https://issues.redhat.com/browse/OCM-139 brings in the support for the setting IMDSv2.

The requirements on how to expose this in the UI are:

• There is a need to expose a new configuration value which can have one of two values:
  • "use both IMDSv1 and IMDSv2" (default) 
  • "use IMDSv2 only"
• Technically it is a machine pool scoped setting which can be changed per machine pool. But the requirement is to set this only once per cluster. All the machine pools will be using this one setting
• This is a day1 only setting. Once the cluster is installed, this can not be changed. Also all the machine pools added in day2 will use the setting configured on cluster creation
• There are no restrictions on when is this allowed (e.g. it works with all OCP versions)
