This reverts commit 15db2d6990.
While this works fine if we trigger the control plane upgrade on
the active controller first, it fails miserably if we upgrade the
inactive controller first.
The fix is to revert this and instead do it in sysinv-conductor, as
covered in https://bugs.launchpad.net/starlingx/+bug/1999095
