K8s application audit should be allowed when k8s upgrade is completed

[Angie Wang]

Brief Description
-----------------
Sysinv platform application audit is blocked when there is a k8s upgrade in progress(It checks for the existence of k8s upgrade DB entry). The audit should be allowed when k8s upgrade is completed(upgrade shows state 'upgrade-complete') as it's already fully upgraded at this stage otherwise the audit gets blocked when users forget to delete the upgrade after it's completed.

    Allow k8s application audit when k8s upgrade is completed

    K8s application audit should be allowed when k8s upgrade is
    completed. At this stage, k8s is already fully upgraded and
    it's safe to do the application operations.
