Allow FluxCD to be upgraded from N to N+1

Browse Source 
With the introduction of [1] FluxCD needs to be updated.
Enhancing upgrade-fluxcd-controllers.yml to allow FluxCD
upgrades is done part of [2].

When upgrading from 22.06 we need the flux manifest to be reapplied
(and pods will be restarted part of the new deployment).
This is designed future proof, upgrading from generic N to N+1 would
work.

Tests on AIO-SX:
Using the load for [2], emulated upgrades call.
PASS: Observed no pod restart when emulating upgrade from 21.12 as there
should be no pod in the first place when coming from 21.12
/etc/upgrade.d/62-enable-fluxcd-controllers.py 21.12 22.12 activate
PASS: Observed pods restart picking the new manifests whe emulating
upgrade from 22.06
/etc/upgrade.d/62-enable-fluxcd-controllers.py 22.06 22.12 activate
