Ironic bare metal console logs only show the last boot

[Dmitry Tantsur]

For every ironic job we publish the console logs from a "bare metal" machine, e.g.
http://logs.openstack.org/61/234861/7/check/gate-tempest-dsvm-ironic-pxe_ipa-src/6c076cf/logs/ironic-bm-logs/

Unfortunately, this file gets truncated on every reboot, so it always contains only the last boot. Which was acceptable - until we introduced cleaning. Now the boot for cleaning always goes last, so logs from deploy are always lost.

We need to somehow store logs from all boots.

Marking it as high because losing the logs is not ideal when debugging Ironic failures (especially gate problems)

    Keep the console logs for all boots

    This patch adds a libvirt hook that saves the VM console log everytime
    it shutdown. This is great for troubleshooting because it allow us to
    see what happened with the VM on every boot instead of only the last one.
