    Add api to query an upgrade is in progress

    Add api to query an upgrade is in progress. This is to
    support kickstarts to avoid processing installer RPMs
    in future releases.

    This change introduces a new sysinv API to query if an
    upgrade is in progress (i.e, upgrade starts, but not
    abort).

    TCs:
        Upgrade from 21.05 -> 21.12 abort after controller-1
            upgrade completed
        Upgrade from 21.05 -> 21.12
        Upgrade from 21.12 -> 22.02 abort after controller-1
            upgrade completed
        Upgrade from 21.12 -> 22.02
        load delete after 21.05 -> 21.12 upgrade abort
        load delete after 21.05 -> 21.12 upgrade complete
        load delete after 21.12 -> 22.02 upgrade abort
        load delete after 21.12 -> 22.02 upgrade complete
