    Disable ansible logging when invoked via subprocess

    Overwrite the default ansible log path in sysinv-conductor.
    The output of ansible playbook executed by conductor is already
    directed to sysinv log. The default ansible logging to the
    playbook user's home directory (/root in this case) is unnecessary
    and can exhaust rootfs over time.

    Test:
      - restart sysinv-conductor
      - verify that the kube networking and static images playbooks
        are executed and output are logged in sysinv log
      - verify that /root/ansible.log does not exist
