Exclude incorrect user events, better pagination
    
    This patch fixes the issue where data is inconsistent because it
    will no longer silently timeout on paginated queries to datagrepper
    and subsequently ignore that container, this scenario is now handled
    gracefully and failed attempts to query are reported to Ansible.
    
    Also resolved in this patch is the exclusion of an tag operation
    that wasn't done by the correct koji user (containerbuild at this
    time).
