    Set cluster-partition-handling on upgrade-charm.

    For units deployed before the implementation of the
    cluster-partition-handling strategy they won't have that key set in the
    leader making the charm believe there are pending tasks, so this change
    seeds the key when is not set with the value present in the charm's
    configuration.
