Revert "prevent pod deployment deadlock due to custom SA projected volume injection"

This reverts commit 9bde7bb, openshift#585.

It was a temporary workaround in 4.8 to bridge a gap between
Kube-API-server and Kube-controller-manager during 4.7 -> 4.8
updates. Once the cluster has reconciled 4.8, we will no longer need
the crutch.  And 4.8 has now forked off master, so we can revert now,
and that revert will go out in 4.9.
