    Retry plugging ports when clustered instances start

    After a while, the Failover Cluster will stop retrying when attempting
    to bring back up failed instances. For example, if the CSV is down
    more than a few minutes, the cluster groups will be set in "Failed"
    state, while the VMs won't be registered on any Hyper-V node.

    The issue is that we're only handling cluster group owner changes
    (moved instances). If the admin fixes the issue and manually brings
    the cluster groups back up, the instances are recreated but we aren't
    handling this, so ports won't get reconnected.

    This change will double check the ports when clustered instances
    start.
