Even after getting this to run, which requires bumping the hyperkube version to 1.25 or above - There's a new error --

│ E0314 21:06:41.648582       1 run.go:74] "command failed" err="strict decoding error: unknown field \"algorithmSource\", unknown field \"leaderElection.lockObjec │

The full information is here, but a rewrite is needed to use this in 1.25

openshift/cluster-kube-scheduler-operator#197 (comment)

What this means is converting the policy configuration defined in the policy.cfg file to use the new profile config spec outlined above in the v1 API.
