  - increase number of open files for collectd

    for collectd KPIs we need may need to open 10,000+ files

    one file for each core * number of CPU counters we read.

    Use the ansible pam_limits moules to increase the nofile
    setting.  This should allow the VNF to boot with increased
    number of files open

  - task: drain background runner queues

    We were not draining the queues in the background
    runners.

    Modify the main runner_join loop to loop over
    all the runners and drain them.

    The runner join method does extra work for periodic actions
    so we can't change its behavior.

    Instead create a new poll() method and use that
    to check runner status
