ovn version differences on ovn-chassis and ovn-central cause "mismatch with northd version" and chassis unable to register to centrals

[Diko Parvanov]

ovn-chassis and ovn-central charms sync ovn packages from different repos, because of different versions in both of them:

ovn-central (focal-updates/yoga/main):
 ovn-common | 22.03.2-0ubuntu0.22.04.1~cloud1 | yoga | focal-updates | linux-any all

ovn-chassis (focal-updates/ovn-22.03/main):
 ovn-common | 22.03.0-0ubuntu1~cloud0 | ovn-22.03 | focal-updates | linux-any all

This needs to be addressed, as during migration from ovs to ovn this causes the ovn-chassis to not be able to register with the central units with:

2023-08-10T07:28:24.235Z|02840|main|WARN|controller version - 22.03.0-20.21.0-58.3 mismatch with northd version - 22.03.2-20.21.0-61.4

The workaround is to use this to prevent the check, but if left there it's dangerous during future upgrades of ovn:

ovs-vsctl set open . external_ids:ovn-match-northd-version="false"

    Make version pinning optional

    The OVN charms prepared for the upgrade from OVN 20.03 to newer
    versions by enabling the version pinning by default.

    Since then we have reached agreement with upstream that rolling
    upgrades should work when upgrading within the previous upstream
    LTS version and the next.

    Having the pinning enabled by default causes unnecessary grief for
    anyone already upgraded to OVN 22.03, so it's time to turn it off
    by default.

    We add a charm configuration option in case anyone wants to
    upgrade across LTS boundaries in the future.
