Commit a075230e4a0f ("Use ct_mark for masked access to make flows
HW-offloading friendly.") started using the ct_lb_mark action instead of
ct_lb. In usual scenarios this new feature would be picked up when the
next stable release becomes available (i.e., 22.06.0). However, the
commit was also backported to stable branches (branch-22.03 and
branch-21.12).
While the supported upgrade scenario for OVN when moving to a new
stable release is to ensure that ovn-controllers are upgraded first,
it's not really clear that this restriction applies to "z-stream"
upgrades too (e.g., from v21.12.1 to v21.12.2).
Some CMSs, like RHEV (Red Hat Virtualization), expect ovn-controllers
running older code from a stable branch to be able to interpret all
Southbound contents generated by ovn-northd instances built from the
same or newer versions of the stable branch.
Ensure that ct_lb_mark is used only when all chassis registered in the
Southbound support it.

NOTE: If accepted, this patch should be backported to branch-22.03 and
branch-21.12. The alternative is to revert a075230e4a0f and its
dependents from all stable branches.
