    [PTP SyncE] Set ice-gnss thread prio in puppet

    Problem: The ice-gnss thread is not spawned until ptp services are
    configured, so on first time setup, the affine-process.sh script is not
    able to set the priority of the thread because it runs before puppet.

    This change adds a task to the puppet manifest to also set the niceness
    of the ice-gnss threads in order to handle the case of first time setup.
    Subsequent lock/unlocks will handled earlier in the startup process by
    affine-process.sh.

    See https://review.opendev.org/c/starlingx/utilities/+/839795 for the
    earlier change to affine-process.sh.

    Testing:

    Pass: Thread niceness set correctly on first time setup on AIO-SX.
    Niceness is also correctly set on subsequent lock/unlocks. Switching
    node from ptp to ntp and back also results in correct priority.
