Users would desire to create EFA instance MachineSet in the same AWS placement group to get best network performance within that AWS placement group.

The Scope of this Epic is only to support placement groups. Customers will create them.
The customer ask is that placement groups don't need to be created by the OpenShift Container Platform
OpenShift Container Platform only needs to be able to consume them and assign machines out of a machineset to a specific Placement Group.
