    Parameters:
    
    instanceInfo - The instance info whose status we care about.
    
    existingLease - Does the instance have an existing lease already? If so let's consider that.
    
    isReplication - When overriding consider if we are under a replication mode from other servers.

    A result with whether we matched and what we propose the status to be overriden to.
