    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.
