[Bug 2115328] [NEW] [uca][zed][antelope][bobcat] Upgrade failure due to missing patches

[Frode Nordahl]

Public bug reported:

The charmed OpenStack product currently make use of a step by step
upgrade process.

This includes stepping through interim releases of OVN.

While OVN itself supports direct upgrades between LTS versions, it is
impractical in the current organization of apt repositories.

Between 22.03 and 22.04 releases, two new actions has been introduced
and backported to resolve critical issues.

These patches have made their way into the ovn 22.03 package in Jammy,
but not to the intermediate versions currently maintained in UCA.  As a
consequence, when users attempt to upgrade they will hit an data path
impacting issue, and find messages below logged by the ovn-controller:

2025-06-19T06:14:46.085Z|00025|lflow|WARN|error parsing actions "ct_commit_nat;": Syntax error at `ct_commit_nat' expecting action.
2025-06-19T06:14:46.089Z|00026|lflow|WARN|error parsing match "flags.from_ctrl && udp.src == 53": Syntax error at `flags.from_ctrl' expecting field name.

The required patches to resolve this are:
474bdfcad038 ("Skip only OVN DNS responder packets from OUT_ACL.")
650f06b9f3e2 ("northd: Allow related traffic through LB")
31196346fcad ("actions: Add new action called ct_commit_nat")
