    Add a log extension

    The log extension is responsible for retrieving logs from the system,
    if journalctl is present the logs will come from it, otherwise we
    fallback to getting the logs from the /var/log directory + dmesg logs.

    In the coreos ramdisk, we need to bind mount /run/log in the container
    so the IPA service can have access to the journal.

    For the tinyIPA ramdisk, the logs from IPA are now being redirected to
    /var/logs/ironic-python-agent.log instead of only going to the default
    stdout.

    Inspector now shares the same method of collecting logs, extending its
    capabilities for non-systemd systems.
