Bug Description

Currently, after downloading the latest image, system-image-cli reboots the system.

It would be extremely useful if rather than hard-coding this, system-image-cli could conditionally call a hook script when it has finished. Ideally, it would be possible to specify this in /etc/system-image/client.ini

Since the desired behaviour could well be device/environment specific, maybe the reboot ability should also be pulled out of systemimage/reboot.py so that by default, /etc/system-image/hooks/default -> /etc/system-image/hooks/reboot.sh gets run, but that could be overriden via client.ini.

We have a [hooks]reboot setting in client.ini. The way to address this would be to add an appropriate implementation in a separate callable, and then point client.ini to this alternate implementation.

The existing hook mechanism is fine IMO, the ubuntu-core-upgrader uses the "reboot" hook to apply the update successfully. The only wart left here is bug #1381538 - i.e. the name "reboot" for the hook is misleading because the core image will not always reboot, only when there are new kernels.

Also, from the snappy branch:

system-image (2.5-0ubuntu1+ppa9) utopic; urgency=low

  * systemimage/data/client.ini:
    - use ubuntucoreupgrader.apply.ApplyUpgrade as the reboot hook

but I think this is a config file change.
