Restore lowlatency pxeboot install menus

Issue found when attempting to install a worker
node that is configured as lowlatency
Expecting the realtime kernel after
host reinstall and host-unlock
instead kernel switched back to standard kernel
image.

Restoring pxeboot kernel install menus

PASS - AIO-SX: iso install

PASS - Standard with Compute/Worker:
        * iso install
        * host-reinstall worker node

PASS - AIO-DX:
        * iso install
        * bootstrap rt-kernel
          and verify rt kernel installed
          on controller-1
        * host reinstall standby controller-1
        * swact and reboot controllers
        * upgrade test

PASS - Worker node/AIO controller node
        * host reinstall
            -> standard kernel image
            -> real time kernel/lowlatency image
        * host lock/unlock
        * host reboot

PASS - upgrade test
        pxeboot-update-<release>.sh affects
        backwards compatibility.
