    AIO reaffine tasks and k8s-infra during startup

    This update reimplements the affine-tasks init script and service to
    dynamically reaffine tasks and k8s-infra cgroup cpuset on AIO nodes.
    This accomodates CPU intensive phases of work. Tasks are initially
    allowed to float across all cores. Once system is at steady-state,
    this will ensure that K8S pods are constrained to platform cores and
    do not run on cores with VMs/containers.

    This will speedup the first stx-application apply, as well as pod
    recovery after lock/unlock, reboot, and controller swact.

    This script waits forever for sufficient platform readiness criteria
    (e.g., system critical pods are recovered, critical openstack pods
    are running, nova-compute pod is running) before reaffining back
    to platform cores.

    This corrects the pod affinity problem seen on AIO introduced by fix
    for bug: 1826592, commit e513baad44181f667085886007632d0ebf79eeb0,
    i.e., fix allowed the AIO to not timeout, but left pods floating.
