Allow deploying worker nodes with a different CoreOS stream than the default.
When WORKER_POOL_OS_IMAGE_STREAM is set (e.g. "rhel-10"), the worker BMH
manifests and MachineSet hostSelector are configured to use the specified
stream label, and a MachineConfigPool manifest is generated to set
osImageStream for the worker pool.

This enables testing heterogeneous clusters where workers boot with a
different IPA and on-disk OS stream than control-plane nodes.

This depends on openshift/installer#10721

I'm adding some helpers to the installer to make this easier.
