From: Alexander Heinisch <alexander.heinisch@siemens.com>
Currently the installer deploys images embedded to itself.
In many situations this is fine, but for some more demanding requirements
are in place. e.g.:
- enrollment of keys (e.g. Secure Boot),
- setup for disk encryption,
- collection and reporting of device information (serial number, mac addresses, ...)
- resize / repartition of disk during comissioning
- generation of a commissioning report
While many of these tasks can be done on first-boot doing so during
device setup can be beneficial in many cases.
e.g.
- additional time required for "first-boot" when performing tasks
with high effort on site may not be desired
- the comissioning environment oftentimes allows for failures during
that phase - worst case the device is put aside. On site failures during
the wrong bootstrapping phases (secure boot setup, disk encryption)
can be severe.
This patch extends current installer behaviour to support a flexible
framework to define multiple tasks to be executed in sequence during
the "target (device) bootstrapping" phase.

The image is now deployed as part of the target-bootstrapper so there
is no need for a separate service like this.
