[microos] Add test for kured reboot method
With the upcoming introduction of "kured" as another reboot method there needs to be some way to choose which method is supposed to be used. This is done by introducing the configuration file /etc/transactional-update.conf.
The configuration file is sourced after the definition of default variable values, so it is possible to redefine those. This may be a useful (undocumented) side effect, but it may also be worth to consider doing the import earlier to allow only a fixed set of variables (i.e. those mentioned in the man page). While it would be trivial to implement there's no mechanism for overriding default files (e.g. /usr/etc/transactional-update.conf) added yet. Instead the configuration options are listed in a separate manual page transactional-update.conf(5).
