    Keep user overrides during app update

    It was observed when updating the app part of platform upgrade that
    it loses user overrides. I suspect a day 0 slip. All the other apps
    already have a flag enabled to keep the user overrides during
    app updates.

    Enable 'maintain_user_overrides' flag, if present on N+1 version then it
    will keep the N version user overrides.

    If there are any kind of user overrides that need transformation
    between N->N+1 update, these must be handled in the upgrade scripts,
    helm charts or in the lifecycle hooks(maybe create new lifecycle
    hook for this purpose).

    Tests:
    PASS: tested stx.5.0 to stx.6.0 upgrade, with patched
          platform-integ-apps, user overrides are kept
